Document Type and Number:
Japanese Patent JP3031602
Kind Code:
B2
Abstract:
PURPOSE: To obtain an ink which does not undergo vol. shrinkage and has improved polymerizability and through-hole-protecting properties by incorporating a specific monoester compound a thermal polymerization catalyst and a photopolymerization catalyst into the ink.
CONSTITUTION: This ink is prepd. by compounding 1-99wt.% monoester compd. represented by formula I or II [wherein R1 is H or methyl; R2 is H or 1-4C alkyl; and Y is alkylene or -(CnH2nO)p-CH2- (wherein n is 2-6; and p is 1-19)] and formed from a polycarboxylic acid and an alcohol having a vinylic unsatd. group, 0.01-20wt.% thermal polymn. catalyst, 0.01-20wt.% photopolymn. catalyst, and, if necessary, 5-90wt.% inert solid powder opaque to ultraviolet rays and up to 70wt.% at least one resin selected from among a phenol resin, a cresole resin, and a rosin resin having a softening point of 60°C or higher and an acid value of 50-500.
