CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is based on and claims the benefit of priority from Japanese Patent Application Serial No. 2019-175382 (filed on Sep. 26, 2019), the contents of which are hereby incorporated by reference in their entirety. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present disclosure relates to a dental curable composition having excellent storage stability. 
     Description of the Related Art 
     In the dental field, a curable composition containing a polymerization initiator consisting of an organic peroxide and their reducing agent and a polymerizable monomer has been widely used as a dental cement, a dental adhesive material, a dental autopolymerizing resin, a dental pretreatment material, and a dental abutment building material and the like. 
     Paste-like multi-part type curable compositions using an oxidation-reduction reaction of an organic peroxide and a reducing agent thereof as a polymerization initiation reaction have been publicly known, and among them, a multi-part type curable composition using a benzoyl peroxide as an organic peroxide and an aromatic amine as a reducing agent thereof has especially high curability and has been used wider. However, when storing under conditions of high environmental temperature, there is a problem that the storage stability is low and the color changes to yellow or brown occur. As a solution to this problem, a multi-part type curable composition using a hydroperoxide which is an organic peroxide and a thiourea derivative which is a reducing agent thereof is disclosed (Prior Document 1). Although the storage stability and the color tone stability of these multi-part type curable compositions are improved  as compared with conventional compositions using a polymerization initiator, the curability is insufficient. 
     Further, as a technique for overcoming the above problems, a multi-part type curable composition containing a transition metal compound of the period 4 in the periodic table such as a copper compound and a vanadium compound as a polymerization accelerator, in addition to hydroperoxide which is an organic peroxide and a thiourea derivative which is a reducing agent thereof is presented (Prior Document 2). Although the curability of these multi-part type curable compositions is dramatically improved, there is a problem that the storage stability is insufficient.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present disclosure will be described in detail below. The (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table of the present disclosure will be described. 
     The transition metal compound of the period 4 in the periodic table refers to a metal compound of groups 3 to 12 of the period 4 in the periodic table, and specifically, each metal compounds of scandium (Sc), titanium (Ti), vanadium (V), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn) can be used without any limitation. Although each of the above transition metal elements may have a multiple valences, they can be added to the curable composition of the present disclosure as long as the valence is stable. Examples include Sc (trivalent), Ti (tetravalent), V (trivalent, tetravalent or pentavalent), Cr (divalent, trivalent or hexavalent), Mn (divalent to heptavalent), Fe (divalent or trivalent), Co (divalent or trivalent), Ni (divalent), Cu (monovalent or divalent), Zn (divalent). Specific examples of the transition metal compound include scandium iodide (trivalent) and the like as a scandium compound,  titanium chloride (tetravalent), titanium tetraisopropoxide (tetravalent) and the like as titanium compounds, acetylacetone vanadium (trivalent), divanadium tetraoxide (tetravalent), vanadylacetyl acetonate (tetravalent), vanadium stearate oxide (tetravalent), vanadyl oxalate (tetravalent), vanazyl sulfate (tetravalent), oxobis (1-phenyl-1,3-butandionate) vanadium (tetravalent), bis (maltlate) oxovanadium (tetravalent), vanadium pentoxide (pentavalent), sodium metavanadate (pentavalent) and the like as a vanadium compound, manganese acetate (divalent), manganese naphthenate (divalent) and the like as manganese compounds, iron acetate (divalent), iron chloride (divalent), iron acetate (trivalent), iron chloride (trivalent) and the like as an iron compound, cobalt acetate (divalent), cobalt naphthenate (divalent) and the like as a cobalt compound, nickel chloride (divalent) and the like as a nickel compound, copper chloride (monovalent), copper bromide (monovalent), copper chloride (divalent), copper acetate (divalent) and the like as a copper compound, and zinc chloride (divalent), zinc acetate (divalent) and the like as a zinc compound. 
     Among these, a trivalent or tetravalent vanadium compound and a divalent copper compound are preferable. Among them, because of having higher polymerization accelerating ability, a trivalent or tetravalent vanadium compound is more preferable, and a tetravalent vanadium compound is most preferable. A plurality of kinds of these transition metal compounds in the period 4 in the periodic table may be used in combination, if necessary. The content of the transition metal compound to be compounded is preferably within a range of 0.001 to 1 parts by weight, more preferably within a range of 0.005 to 0.5 parts by weight, based on 100 parts by weight of the total amount of all polymerizable monomers. When the content is less than 0.001 parts by weight, there is a case where the polymerization accelerating effect is insufficient, and when the content exceeds 1 parts by weight, there is a case where it causes discoloration or gelation of the curable composition, and the storage stability is lowered. 
     As the inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table (hereinafter, also simply referred as “non-reactive inorganic particle” in the present specification), any inorganic particle can be preferably used as long as the inorganic particle not only does not react with the transition metal compound of the period 4 in the periodic table (hereinafter, also simply referred as “transition metal compound” in the present specification), but also does not interact  with an oxidation-reduction reaction of an organic peroxide and a reducing agent thereof. As the non-reactive inorganic particle, oxides such as silica, zirconia, calcium, titania and alumina, composite oxides (glass) thereof, metal fluorides such as trifluoroitterbium and sodium fluoride, sulfates such as magnesium sulfate and barium sulfate can be used. Among these, composite oxides, metal fluorides and sulfates are preferable, and especially trifluoro ytterbium and barium sulfate are more preferable. A plurality of kinds of these non-reactive inorganic particles may be used in combination, if necessary. The primary particle diameter of the non-reactive inorganic particles is preferably within a range of 0.01 to 50 μm, more preferably within a range of 0.01 to 20 μm from the viewpoint of dispersibility. When the primary particle diameter of the non-reactive inorganic particles is less than 0.01 μm, there is a case where the cohesiveness becomes high and the dispersibility into the polymerizable monomer is lowered, and when the primary particle diameter of the non-reactive inorganic particles is more than 50 μm, there is a case where the non-reactive inorganic particles are non-uniformly dispersed in the composition and it is difficult to sufficiently accelerate the polymerization. 
     Further, as for the shape, any non-porous particle can be used without any limitation, and examples thereof include a spherical shape, a crushed shape, and an indefinite shape. In a case of a porous particle, an opportunity to react the transition metal compound adsorbed in the pores as a polymerization accelerator reduces, therefore the polymerization accelerating efficiency may be lowered and an unreacted residue may be prepared to cause discoloration. Therefore, the pore volume of the non-reactive inorganic particle in the present disclosure is 0.2 cc/g or less, preferably 0.15 cc/g or less, and most preferably 0.1 cc/g or less. The pore volume, for example, can be determined by the BJH method, and the pore volume is that of the aggregated particle when the non-reactive inorganic particle is an aggregated particle. 
     As for a method for adsorbing a transition metal compound to a non-reactive inorganic particle, both a physical adsorption method and a chemical adsorption method can be used without any limitation. Specifically, chemical adsorption methods such as a hydrophobic adsorption, a deposition-precipitation method, an impregnation method, a coprecipitation method, an ion exchange method and an equilibrium adsorption method and physical adsorption methods can be used, but physical adsorption method  is preferable from the viewpoint of production efficiency. More specifically, a method of obtaining a transition metal adsorbent adsorbing a transition metal compound by dissolving or dispersing in an organic solvent having a high affinity with the transition metal compound and having a low boiling point, and removing the organic solvent after mixing with non-reactive inorganic particles, and a method of depositing a transition metal particle on the surface of an inorganic particle by adding a poor solvent after dissolving in a good solvent having a high affinity with a transition metal compound, and a method of physically adsorbing a transition metal compound on the inorganic particle surface by using a pot mill, a ball mill, a planetary mill and the like are preferable. 
     The adsorption amount of the transition metal compound on the non-reactive inorganic particle is preferably within a range of 0.001 to 0.1 g/m 2 , more preferably within a range of 0.001 to 0.05 g/m 2  in terms of the adsorption amount per unit area of the inorganic particle. When the amount is less than 0.001 g/m 2 , there is a case where the polymerization accelerating effect is insufficient, and when the amount is more than 0.1 g/m 2  or more, there is a case where the polymerization accelerating effect is excessive, and therefore discoloration and the like occurs and the storage stability is lowered. In the present disclosure, when a plurality of the (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table are contained, it is preferable that the adsorption amount of any one of the (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table is within the above range, and it is more preferable that the adsorption amounts in all (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table are within the above range. 
     The content of the (a) transition metal adsorbent in which a transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table to be compounded is preferably within a range of 0.05 to 7.5 parts by weight, more preferably  within a range of 0.05 to 5 parts by weight, based on 100 parts by weight of the total amount of the polymerizable monomer. When the content is less than 0.05 parts by weight, there is a case where the ability as a polymerization accelerator is insufficient, and when the content exceeds 7.5 parts by weight, the discoloring may be caused by localization. 
     Any known thiourea derivatives can be used as the (b) thiourea derivative of the present disclosure without any limitation. Specific examples of the thiourea derivatives include dimethylthiourea, diethylthiourea, tetramethylthiourea, (2-pyridyl) thiourea, N-methylthiourea, ethylenethiourea, N-allylthiourea, N-allyl-N′-(2-hydroxyethyl) thiourea, N-benzylthiourea, 1,3-dicyclohexyl thiourea, N,N′-diphenylthiourea, 1,3-di(p-tolyl) thiourea, 1-methyl-3-phenylthiourea, N-acetylthiourea, N-benzoylthiourea, diphenylthiourea, dicyclohexylthiourea and the like. Among these, N-acetylthiourea and N-benzoylthiourea are preferable. A plurality of kinds of these thiourea derivatives can be used in combination, if necessary. The content of the thiourea derivative to be compounded is preferably within a range of 0.1 to 4 parts by weight based on 100 parts by weight of the total amount of all polymerizable monomers.

The content of the organic peroxide having a hydroperoxide group to be compounded is preferably within a range of 0.1 to 3 parts by weight based on 100 parts by weight of the total amount of all polymerizable monomers. When the content is less than 0.1 parts by weight, there is a case where the ability as a polymerization accelerator is insufficient, and when the content exceeds 3 parts by weight, the storage stability may be lowered.

     Preparing Method of Paste 
     For each of the first paste or the second paste shown in Tables 1 to 3, the (b) thiourea derivative, the (c) organic peroxide having a hydroperoxide group, the (d-1) acidic group-non-containing polymerizable monomer, the (d-2) acidic group-containing polymerizable monomer and others were added in a mixing container, and mixed by using a mix rotor VMRC-5 under the condition of 100 rpm for 24 hours to prepare a resin solution. Then, the filler and the (a) transition metal adsorbent in which a  transition metal compound of the period 4 in the periodic table is adsorbed on an inorganic particle which is non-reactive with a transition metal of the period 4 in the periodic table were put into a kneading container, and kneaded by using a rotation and revolution mixer ARV-300 at 1400 rpm for 20 minutes to prepare a first paste and a second paste. Prepared first paste and second paste were filled into the double syringe of 5 mL manufactured by Mixpack (volume ratio of first paste to second paste is 1:1) so as to have a predetermined weight component ratio to prepare Compositions 1 to 31 as a two-paste type dental polymerizable composition. 
     Measuring Method of Average Particle Diameter 
     After ultrasonic wave was applied to the inorganic particles for 1 minute by using a particle size analyzer Microtrack MT3300EXII (manufactured by Nikkiso Co., Ltd.), the particle size was measured. Further, for samples having an average particle diameter of 200 nm or less, a picture of the inorganic particles was taken at an arbitrary magnification with a scanning electron microscope (Hitachi Science Systems Co., Ltd.: SEMEDX3 Type N), and the taken image was processed by using image analysis software, and a circle-equivalent diameter of 50 primary particles was measured, and then the average particle diameter was calculated based on the measured values. 
     Measuring Method of Pore Volume and Specific Surface Area 
     By using QUADRASORB evo (manufactured by Quantachrome Instruments), a specific surface area was measured by the BET multipoint method and a pore volume was measured by the BJH method. Note that before measuring, the inorganic particles were pretreated (heating at 200° C. under vacuum degassing for 2 hours) and adsorbed water was removed.

      The test method of each characteristic evaluated in the example and the comparative example is as follows. Each test was carried out under the conditions of automatic mixing with the mixing tip attached. 
     Curing Time Measurement 
     Curing time of the kneaded material of the pastes A and B was measured according to ISO 4049: 2009. Specifically, 0.8 g of the kneaded paste was filled in a container (4 mmφ×6 mm: manufactured by Teflon) attached with a thermocouple, and an exothermic curve due to a curing reaction was recorded. The time from the start of kneading of the paste to the peak of the exothermic curve was taken as the curing time, and the three measurements were averaged. 
     Stability of Curability 
     The above described curing time immediately after preparation of the paste was compared with that after storage at 40° C. for 5 months. The rating criteria were as follow: 
     S: The change rate was less than ±20%.
 
A: The change rate was 20% or more and less than 40%, or −20% or less and more than −40%.
 
B: The change rate was 40% or more and less than 60% or −40% or less and more than −60%.
 
C: Gelled or uncured

     Paste Stability 
     Color Difference 
     The paste was discharged from the syringe, and the color tone (CIE L*a*b*) of the paste compounded with the transition metal compound was measured for immediately after preparation and after storage at 40° C. for 5 months, and then the color difference ΔE was calculated. The rating criteria were as follow: 
     S: ΔE was 0 or more and less than 2. 
 
A: ΔE was 2 or more and less than 4.
 
B: ΔE was 4 or more and less than 8.
 
C: ΔE was 8 or more.
 
     As the specific color measurement method, the paste was sampled in a mold with a thickness of 1.0 mm and an inner diameter of 15 mm, both ends were fixed with a thin glass plate with a thickness of 0.15±0.02 mm, and color measurement in a state of the thickness of 1.0 mm was performed under the conditions of SCE and a white background by using a colorimeter (CM-26d: manufactured by Konica Minolta). 
     Characteristics 
     Equal amounts of the first and the second pastes were discharged from the syringe, the feeling of kneading was confirmed by using a spatula. The rating criteria were as follow: 
     A: There was no change between the pastes immediately after preparation and after storage at 40° C. for 5 months.
 
B: There was slightly hardening between the pastes immediately after preparation and after storage at 40° C. for 5 months.
 
C: The change that makes clearly difficult to use such as gelation was observed.
 
     The above tests were performed for compositions 1 to 48, and Table 4 shows the results. Compositions 1 to 17, 21, 22, 25 to 30, and 32 to 46 that satisfied storage stability and color stability are respectively described as Examples 1 to 40.

      In Examples 1 to 40 in which each component satisfies the constitution of the present disclosure, even after storage at 40° C. for 5 months, the composition was cured, no significant color change was observed, and it could withstand the use for a dental composition applied to the oral cavity, and therefore high storage stability was exhibited. Further, in Examples 7, 11, 14 to 16, 18 to 25, 37, 38, it was confirmed that although the curing time after storage at 40° C. for 5 months was shortened or delayed, it was not a significant change in operation. 
     For Example 11, although the reason was unknown, it was considered that the polymerization accelerating effect was lowered by not containing the (d-2) acidic group-containing polymerizable monomer. 
     For Examples 7, 14, 15 and 16, it was considered that the reactivity of the transition metal compound adsorbed on the spherical silica or the fluoroaluminosilicate glass lowered for some reason. 
     In Examples 18 and 19, the curing time was shortened after storage at 40° C. for 5 months. It was considered that these were caused by an excessive compounding amount of the (b) thiourea derivative or the (c) organic peroxide having a hydroperoxide group. 
     For Examples 20 and 38, it was considered that shortening or delay in curing time occurred because a content of a transition metal compound was slightly excess with respect to the (b) thiourea derivative and the (c) organic peroxide having a hydroperoxide group. 
     In Examples 22, 24 and 26, it was considered that a slight discoloration was caused since the adsorption amount of transition metal was slightly large and the transition metal compound was localized in the composition.  
     In Examples 21, 23, 37, a slight delay was observed in the curing time after storage at 40° C. for 5 months. It is considered in Example 21 that the reason is that the transition metal compound was too little with respect to the (b) thiourea derivative and the (c) organic peroxide having a hydroperoxide group, and in Example 20 that the adsorption amount of transition metal of the transition metal adsorbent was too little. 
     In the composition of Example 25, the respective pastes in which the (b) thiourea derivative and the (c) organic peroxide having a hydroperoxide group were contained in Example 16 were replaced from each other, and a shortening of the curing time within an allowable range was observed. It was considered that the activity was unintentionally increased by compounding the (c) organic peroxide having a hydroperoxide group and the transition metal compound in the same paste for a long time. 
     For Example 28, it was considered that slight discoloration occurred since the content of the (b) thiourea derivative was slightly little. 
     For Example 30, it was considered that slight discoloration occurred since the content of the (b) thiourea derivative was slightly large. 
     For Example 32, it was considered that slight discoloration occurred since the content of the (c) organic peroxide having a hydroperoxide group was slightly little. 
     For Example 36, it was considered that slight discoloration occurred since the content of the (d-2) acidic group-containing polymerizable monomer was slightly large. 
     For Example 40, it was considered that slight discoloration occurred and paste properties were lowered since the components other than (a) to (d) are not contained.  
     The curing time of these dental compositions can be arbitrarily adjusted by adding a plurality of polymerization accelerators, increasing or decreasing the compounding amount of the polymerization accelerator and increasing or decreasing the adsorption amount of the transition metal compound. Furthermore, since it is possible to adjust physical characteristics such as bending strength, flexural modulus and film thickness by appropriately changing the compounding amount and the particle diameter of the filler and the like, it is preferable to use as a dental two-paste type polymerizable composition such as a dental cement, a dental adhesive material, a dental autopolymerizing resin and a dental abutment construction material. 
     Since Comparative Example 1 did not contain a transition metal compound, it was confirmed that the polymerization accelerating effect was not obtained, the curing time immediately after preparation was extremely long, and the curing did not occur after storage at 40° C. for 5 months. 
     In Comparative Examples 2 and 3, although no significant change was observed in the curing time, discoloration of the composition was observed after storage at 40° C. for 5 months. It was considered that the transition metal compound adsorbed in the pores remained for a long period of time to led discoloration. 
     In comparative Example 4, discoloration was observed after storage at 40° C. for 5 months, and in Comparative Example 5, gelation was observed after storage at 40° C. for 5 months. It was considered that the reason is that since the transition metal compound was not adsorbed on inorganic particles or the like and dispersed in the paste, the transition metal compound was microscopically localized to led discoloration or gelation. Further, although the compounding amount of the transition metal compound of Comparative Example 4 was almost the same as that of Example 1, the curing time was long in Comparative Example 4, therefore it could be considered that the dispersion in the composition was insufficient. 
     In Comparative Example 6, although the curing time immediately after  preparation was appropriate, it was confirmed that the first paste was gelled after storage at 40° C. for 5 months. Although the compounding amount of the transition metal compound was the same as that in Example 1, it was considered that PMMA particles as the adsorbed particles were swelled or dissolved in the polymerizable monomer to release the dispersed state, and the transition metal compound was localized in the composition to induce gelation. In Comparative Example 7 and Comparative Example 8, curing was not achieved.
