Color developing sheet for pressure-sensitive recording systems |
摘要 |
A color developer sheet sensitized in a color developing property on contact with a chromogenic material and improved in the light-resistance of the developed color, which comprises a support sheet and a coating composition comprising an organic color developer and, as a binder, a latex of a copolymer prepared by polymerization of a mixture essentially consisting of about 20 to 70% by weight of one or more aliphatic conjugated diolefin monomers, about 0.5 to 15% by weight of one or more unsaturated carboxylic acid monomers and about 15 to 79.5% by weight of one or more other olefin monomers copolymerizable with them and having a gel content of about 95 to 100% by weight applied onto a surface of the said support sheet to make a color developer layer.
