PURPOSE:To improve color developing capacity and make also a pressure- sensitive recording sheet, by a method wherein photosetting developed ink is prepared by compounding a developer, 3-halo-4-hydroxybenzoate, a photopolymerization initiator and a pigment with, each other. CONSTITUTION:A developer, 3-halo-4-hydroxybenzoate having a polymerizabale ethylene group of a photosetting compound represented by a formula (X shows a halogen atom, Y shows a monovalent group having a polymerizable ethylene group, Z shows H, an alkoxy group and an alkyl group) and a heat-reactive polymerization inhibitor are mixed up with each other, heated and dissolved, through which varnish is prepared. Then a photopolymerization initiator, a pigment and waxes are added to the varnish, kneaded by a three-roll mill and developed ink is prepared. The developed ink is applied to a high-quality paper face and film base face and after spot printing is performed to a part of the coated face where copying is necessary by using a printing machine, the same is cured by irradiation of light. |
