PURPOSE: To obtain the titled composition capable of being used in a heat-sensitive recording sheet and also of forming a picture having excellent resolution on a printing paper by using a crosslinkable resin as a part or all of a binder to be included in the titled composition.
CONSTITUTION: A coloring matter composition is obtained by dispersing 1W 20wt% an organic dye volatilizable from solid or liquid state at 100W200°C, having a comparatively small molecular weight, and 2W40wt% a crosslinkable resin as a binder into a solvent, e.g., water, alcohols, esters, etc. The crosslinkable resin used includes ones consisting of a combination of a natural or synthetic resin having reactive functional groups and a crosslinking agent or a curing agent or of a radiation-curable and crosslinkable resin mixed with a photopolymerization initiator as needed. In this case, in order to obtain a properly crosslinked resin, the amount of the crosslinking agent, etc., is preferably adjusted and also a thermoplastic resin and a plasticizer are preferably added in an amount less than about 30wt% of the total amount of the binder used.
