接着，列举出用于实施本发明的优选的方式，更详细地说明本发明。
Description of Embodiments [0011] Next, the present invention will be described 6 in more detail giving preferred embodiments for carrying out the invention.
本发明人等为了解决前述现有技术中的课题而进行了深入研究，结果获得下述见解，由此完成了本发明。
The present inventors have conducted diligent studies in order to solve the previously described problems in the conventional techniques to obtain the knowledge described below and have completed the present invention.
首先已知：制成未取代喹吖啶酮与2,9-二烷基喹吖啶酮的固溶体颜料时，为了使所得颜料的色调呈偏黄色而需要将其质量比例设为85：15～60：40。
Firstly, it has been found that when a solid solution pigment of unsubstituted quinacridone and a 2,9 dialkylquinacridone is made, the mass ratio of the unsubstituted quinacridone to the 2,9-dialkylquinacridone needs to be 85:15 to 60:40 in order to make the hue of a resultant pigment yellowish.
因此，通过获得在上述质量比例的未取代喹吖啶酮与2,9-二烷基喹吖啶酮的固溶体中包含水的含水状态的粗制喹吖啶酮固溶体，并将其颜料化，从而能够制造偏黄色的喹吖啶酮固溶体颜料。
Therefore, when a water containing crude quinacridone solid solution such that water is contained in the solid solution of unsubstituted quinacridone and a 2,9-dialkylquinacridone, the solid solution having the above-described mass ratio, is obtained, and this solid solution is made into a pigment, production of a yellowish quinacridone solid solution pigment is thereby made possible.
本发明人等为了实现本发明的前述目的而进行了进一步的研究。
[0012] The present inventors have conducted further studies in order to achieve the previously described objects of the present invention.
首先，在上述质量比例的未取代喹吖啶酮与2,9-二烷基喹吖啶酮的固溶体中包含水的含水状态的粗制喹吖啶酮固溶体通过在多聚磷酸中使二芳基氨基对苯二甲酸与二烷基芳基氨基对苯二甲酸发生共环化反应来获得。
Firstly, the water containing crude quinacridone solid solution such that water is contained in the solid solution of unsubstituted quinacridone to a 2,9-dialkylquinacridone, the solid solution having the above-described mass ratio, is obtained by subjecting a diarylaminoterephthalic acid and a dialkylarylaminoterephthalic acid to a co-cyclization reaction in polyphosphoric acid.
在现有的未取代喹吖啶酮与2,9-二烷基喹吖啶酮的喹吖啶酮固溶体颜料的制造方法中，将如此制造的含水状态的粗制喹吖啶酮固溶体在含水状态下在溶剂中加热而实现颜料化。
In a conventional method for producing a quinacridone solid solution pigment of unsubstituted quinacridone and a 2,9-dialkylquinacridone, the water-containing crude quinacridone solid solution produced in this manner is heated in a solvent keeping the water-containing state as it is to be made into a pigment.
根据本发明人等的研究可知：通过这种现有的制造方法进行颜料化而得到的颜料与作为原料的粗制喹吖啶酮固溶体相比偏黄色更明显，无法实现所得着色物的饱和度高且期望的适度的偏黄色调这样的本发明的目的。
According to studies conducted by the present inventors, it has been found that a pigment obtained by pigmentation in such a conventional production method is more yellowish 7 than the crude quinacridone solid solution used as a raw material and does not allow a resultant colored product to have high chroma and a desired, properly yellowish hue, the high chroma and the properly yellowish hue each being an object of the present invention.
本发明人等为了发现如下方法而进行了进一步的研究，所述方法能够改善上述问题，并且着色物呈现市场上期望的饱和度高且适度的偏黄色的良好色调的喹吖啶酮固溶体颜料的制造方法。
The present inventors have further conducted studies in order to find a method for producing a quinacridone solid solution pigment which can improve these points and allows a colored product to have high chroma and a properly yellowish, satisfactory hue, the high chroma and the properly yellowish, satisfactory hue each being desired in the market.
其结果，本发明人等发现：对于上述现有的喹吖啶酮固溶体颜料的制造方法，通过在进行颜料化的工序之前，新设置用于制成粉状的粗制喹吖啶酮固溶体的干燥工序，在该干燥工序中，干燥至水分含量小于1％，然后，进行经干燥的粉状的粗制喹吖啶酮固溶体的颜料化，从而由所得喹吖啶酮固溶体颜料形成的着色物与使用通过现有的制造方法得到的固溶体颜料形成的着色物相比，成为具有高饱和度且适度的偏黄色的良好色调的产物。
[0013] As a result, the present inventors have found that when a drying step for making a powdery, crude quinacridone solid solution is newly provided before the pigmentation step in the above-described conventional method for producing a quinacridone solid solution pigment, and in this drying step, drying is performed until the water content becomes less than 1% to thereafter perform the pigmentation of the dried, powdery, crude quinacridone solid solution, a colored product formed with a resultant quinacridone solid solution pigment has thereby higher chroma and a more properly yellowish hue as compared to a colored product formed using a solid solution pigment obtained by the conventional production method.
另外，根据本发明人等的研究发现：通过将本发明的制造方法制成适合的构成，能够将所得喹吖啶酮固溶体颜料的粒径控制在期望的微细大小。
In addition, according to studies conducted by the present inventors, it has been found that when the constitution of the production method of the present invention is made suitable, the particle diameter of a resultant quinacridone solid solution pigment can thereby be controlled into desired, fine size.
尤其是，根据本发明的优选的方式，也可提供适于要求墨的喷出稳定性的喷墨用墨的粒径的喹吖啶酮固溶体颜料。
Particularly, according to a preferred embodiment of the present invention, a quinacridone solid solution pigment having a particle diameter suitable for an inkjet ink in which ejection stability of the ink is demanded can also be provided.
<喹吖啶酮固溶体颜料的制造方法>
Subsequently, in the next drying step that characterizes the present invention, the above-obtained water-containing crude quinacridone solid solution having a particular composition is dried until the water content becomes less than 1%, thereby obtaining a powdery, crude quinacridone solid solution.
本发明的实施例一般涉及制备包括喷口的封装的方法。
Embodiments of the present disclosure generally relate to processes for making a package comprising a spout.
具有密封配件的柔性袋封装(也称为喷口袋)对于封装多种类型的食品和非食品产品来说越来越受欢迎。
Flexible pouch packaging with sealed fitments, also known as spout-pouches, are increasing in popularity to package many types of food and nonfood products.
喷口袋在可持续性改进、物流链优化、封装品的完全消耗、处理后的空间减少和其它益处方面提供优势。
The spout-pouches offer advantages with respect to sustainability improvement, logistics chain optimization, complete consumption of the packaged product, less space after disposal, and other benefits.
然而，制造喷口袋的制造方法和过程已对用于产生喷口袋的可行材料造成限制。
However, manufacturing methods and processes for making spout-pouches have limited the feasible materials for utilization in spout-pouch creation.
确切地说，传统的用于产生喷口袋的系统通过从形成袋的膜外部借助于恒定加热的密封工具施加热量和压力来利用喷口的热密封。
Specifically, traditional systems for spout-pouch creation have utilized heat sealing of the spout by applying heat and pressure by means of a constantly heated sealing tool from the outside of the film forming the pouch.
因此，热量必须从加热的密封工具，通过袋膜，并传递到袋膜与喷口之间的界面，由此需要高温以产生密封，并传热通过整个膜厚度。
As a result, heat must pass from the heated sealing tools, through the pouch film, and to the interface between the pouch film and the spout thereby necessitating high temperatures to create a seal with heat transfer through the whole film thickness.
另外，贯穿袋膜的整个厚度的必要加热会引起整个袋膜发生软化，其可能导致在喷口固定期间施加压力时变薄并且引入袋的弱点。
Thus, external layers for spout-pouches have been limited to materials with a melting point in excess of 200°C as such materials must contact the heated sealing tool potentially at a temperature of 200°C. Additionally, the necessary heating throughout the entire thickness of the pouch film results in softening of the entire pouch film which may lead to thinning and introduction of pouch weakness when pressure is applied during spout fixation.
因此，存在对用于制造包括喷口的封装的改进方法的持续需求。
Accordingly, ongoing needs exist for improved processes for making a package comprising a spout.
具有根据本发明方法的一些实施例制造的具有喷口的封装未展现密封层的膜厚度的显著降低。
Packages with spouts produced in accordance with some embodiments of processes of the present disclosure do not exhibit a significant reduction in film thickness of the sealing layer.
具有喷口的传统封装会出现膜厚度变薄，这是由于加热整个膜厚度和整个密封层的熔融以及在喷口安装期间施加的挤压压力造成。
Traditional packages with spouts have a thinning of the film thickness resulting from heating the entire film thickness and melting of the entire sealing layer in combination with an applied squeezing pressure during spout installation.
本发明的各种方法实施例，以及在所述方法中使用的特定膜满足这些需求中的一种或多种。

所述实施例的额外特征和优点将阐述于以下具体实施方式中，并且部分地将由所述描述而对于所属领域中的技术人员显而易见，或通过实践所述实施例(包含以下具体实施方式、权利要求书以及附图)而得到认识。

其结果可知：进行颜料化而最终得到的喹吖啶酮固溶体颜料具有高饱和度且适度的偏黄色的良好色调。
As a result, it has been found that a quinacridone solid solution pigment which is finally obtained through the pigmentation has high chroma and a properly yellowish, satisfactory hue.
