Abstract:
A composition for coating and printing for baking finish, which contains one or two or more benzoguanamine compounds (A) having a radically polymerizable double bond and condensation-polymerizable functional group in its molecule and one or two or more radically polymerizable modified (meth)acrylate compounds (B), wherein the compound (A) is a compound represented by the formula (I): wherein R1 is phenyl; R2 is H, an alkyl group having 5 to 18 carbon atoms, cyclohexyl, phenyl or R3, R4 or R5 described below; n is O or an integer of 1 to 3; provided that at least one of R2 in one molecule is R3, R4 or R5, in which R3 is a group represented by the formula:â€”Xâ€”OCOâ€”CY&boxH;CH2 in which Y is H or â€”CH3; X is alkylene having 5 to 18 carbon atoms and a part or a whole of its hydrogen atoms may be substituted by halogen atom, R4 is a group represented by the formula:â€”(Vâ€”O)mâ€”Zâ€”OCOâ€”CY&boxH;CH2 in which Y is as defined above; any of V and Z are a linear or cyclic alkylene group having 2 to 8 carbon atoms and a part or a whole of its hydrogen atoms may be substituted by halogen atom, m is an integer of 1 to 20, and R5 is a group represented by the formula:(Wâ€”COO)pâ€”Zâ€”OCOâ€”CY&boxH;CH2 in which Y and Z are as defined above; W is a linear or cyclic alkylene group having 3 to 8 carbon atoms and a part or a whole of its hydrogen atoms may be substituted by halogen atom, p is an integer of 1 to 8, and the radically polymerizable modified (meth)acrylate compound (B) is(1) an alkyleneoxide-modified (meth)acrylate prepared by reacting (meth)acrylic acid with an alcohol having ethyleneoxide or propyleneoxide adduct, a carboxyalkylester-modified (meth)acrylate prepared by reacting a carboxyalkyl (meth)acrylate with an alcohol, an epoxy-modified (meth)acrylate prepared by reacting acrylic acid or methacrylic acid with an epoxy group of glycidyl ether of an alcohol, a (meth)acrylate having urethane bond and prepared by reacting a (meth)acrylate having hydroxyl with a compound having isocyanate group at its end or a mixture thereof; or (2) a (meth)acrylate-modified epoxy resin prepared by reacting (meth)acrylic acid with an epoxy resin, a (meth)acrylate-modified epoxy resin prepared by reacting (meth)acrylic acid to the epoxy resin modified by the above-mentioned alkyleneoxide or carboxylalkyl, a (meth)acrylate prepolymer or polymer having urethane bond and prepared by reacting a (meth)acrylate having hydroxyl with a compound having isocyanate group at its end, a (meth)acrylate-modified polyester prepared by reacting (meth)acrylic acid with a polyester, or a mixture thereof.
