Abstract:
A metal surface treatment liquid composition that comprises water and the following components:(A) a component of resin molecules that conform to general formula (I): wherein: n represents 0 or an integer from 1 through 29; m represents 0 or an integer from 1 through 10; W represents a moiety selected from the group consisting of: (1) a hydrogen atom moiety; and (2) moieties conforming to one of the general formulas â€”CH2X, â€”CH2NHCH2X, and â€”CH&boxH;NCH2X, in all of which â€œXâ€  represents a moiety selected from the group consisting of: â€”OH; moieties conforming to â€”OR4, wherein R4 is selected from the group consisting of alkyl moieties having from 1 to 5 carbon atoms and hydroxyalkyl moieties having from 1 to 5 carbon atoms; covalently bonded halogen atom moieties; and moieties conforming to one of general formula (III) or general formula (IV): wherein: each of R5, R6, R7, R8, and R9 independently represents a moiety selected from the group consisting of: hydrogen atom moieties; alkyl moieties having from 1 to 10 carbon atoms; and hydroxyalkyl moieties having from 1 to 10 carbon atoms; and Aâˆ’ represents a hydroxyl ion or an anion of an acid; each â€œWâ€  symbol in general formula (I) is independently selected, subject to constraints that:a positive number of the selections for â€œWâ€  are not hydrogen atom moieties; and said positive number of the selections for â€œWâ€  that are not hydrogen atom moieties has a ratio to the number n+m+1, this ratio being denoted hereinafter as the â€œP-ratioâ€ , that is from 0.2:1.00 to 4.0:1.00; R1, independently for each aromatic-ring-containing moiety in the part of formula (I) between the square brackets subscripted by â€œnâ€  and independently for each R1-Z containing moiety in the part of formula (I) between the square brackets subscripted by â€œmâ€ , represents a moiety selected from the group consisting of â€”CH2â€”, â€”CH2â€”NHâ€”CH2â€”, and â€”CH&boxH;Nâ€”CH2â€”; Y, independently for each instance of Y in the general formula and independently for each aromatic-ring-containing moiety in the part of formula (I) between the square brackets subscripted by â€œnâ€ , represents a hydrogen moiety or a moiety that conforms to general formula (II): wherein each of R2 and R3 independently represents a hydrogen atom or an alkyl group with not more than 3 carbon atoms and W, independently for each instance of its occurrence in formula (II), is selected from the group consisting of: (1) a hydrogen atom moiety; and (2) moieties conforming to one of the general formulas â€”CH2X, â€”CH2NHCH2X, and â€”CH&boxH;NCH2X, in all of which â€œXâ€  represents a moiety selected from the group consisting of: â€”OH; moieties conforming to â€”OR4, wherein R4 is selected from the group consisting at alkyl moieties having from 1 to 5 carbon atoms and hydroxyalkyl moieties having from 1 to 5 carbon atoms; covelently bonded halogen atom moieties; and moieties conforming to one of general formula (III) or general formula (IV): wherein: each of R5, R6, R7, R8, and R9independently represents a moiety selected from the group consisting of: hydrogen atom moieties; alkyl moieties having from 1 to 10 carbon atoms; and hydroxyalkyl moieties having from 1 to 10 carbon atoms; and Aâˆ’ represents a hydroxyl ion or an anion of an acid; Z as selected from the group consisting of (1) divalent moieties which: are formed by the loss, from an organic compound that is reactive with formaldehyde in an addition condensation reaction and that contains at least one 5- or 6-membered ring that includes two conjugated double bonds, of two hydrogen atoms, each originally bonded to a carbon atom that was part of said 5- or 6-membered ring; and differ from the aromatic-ring-containing moiety in the part of formula (I) between the square brackets subscripted by â€œnâ€ ; and (2) divalent moieties formed by the loss of one hydrogen atom from each of two distinct amino moieties of melamine, guanamine, and urea; and (B) a component selected from the group consisting of vanadium compounds in which the valence of the vanadium atoms is 5, 4, or 3; and (C) a component selected from the group consisting of compounds that contain at least one metal selected from the group consisting of zirconium, titanium, molybdenum, tungsten, manganese, and cerium.
