Abstract
An ink jet recording sheet which absorbs water-base ink well, gives high-grade images, and ensures excellent water resistance of printed images. The ink jet recording sheet comprises a substrate and an ink receptive layer disposed on the substrate, the ink receptive layer containing a pigment and a binder as its main components, the improvement comprising the ink receptive layer being an aqueous composition containing a pigment and an ampho-ion latex as its main components.
Claims8
An ink jet recording sheet comprising a substrate selected from the group consisting of plastic films and synthetic papers;
- and an ink receptive layer disposed on said substrate, said ink receptive layer consisting essentially of a pigment and a binder, the improvement comprising forming said ink receptive layer by the following steps:
- a) applying to said substrate at least one aqueous composition consisting essentially of a pigment and an amphoteric latex formed by seed polymerization of a carboxylated synthetic rubber latex or synthetic resin emulsion with an alkylamine monomer, said amphoteric latex being present in a range of about 5 to 70 parts by weight per 100 parts by weight of said pigment;
- and
- b) drying.
