Abstract
An ink jet recording sheet containing a basic latex polymer is described, which can provide images, having excellent water resistance properties and high image density, by jetting thereonto an aqueous ink containing a water-soluble dye. In the case of applying a multicolor ink jet recording to the recording sheet, color images having excellent color reproduction are obtained.

An ink jet recording sheet for forming a recorded image by jetting thereonto an aqueous ink containing as a water-soluble dye a direct dye or acid dye having an anionic dissociable group, comprising at least one water insoluble basic latex polymer incorporated in or on a base support.
An ink jet recording sheet for forming a recorded image by jetting thereonto an aqueous ink containing as a water soluble dye a direct dye or acid dye having a anionic dissociable group, comprising at least one water insoluble basic latex polymer incorporated in or on a base support, wherein the basic latex polymer is represented by the formula (I) ##STR17## wherein the polymer unit (A) is represented by formula (II), (III) or (IV) ##STR18## wherein R.sub.1 represents a hydrogen atom or a lower alkyl group having from 1 to 6 carbon atoms;
- R.sub.2, R.sub.3, or R.sub.4 each represents an alkyl group having from 1 to 6 carbon atoms, or an aralkyl group having from 7 to 10 carbon atoms, and said R.sub.2, R.sub.3, and R.sub.4 may combine with each other to form a cyclic structure;
- X.sup..crclbar. represents an anion, and n represents an integer of 0 to 2, wherein the polymeric unit represented by --B-- is derived from a monomer having the formula (V) ##STR19## wherein R.sub.7 represents a hydrogen atom or methyl group, T represents a group bonding to the vinyl group selected from the group consisting of an amide group, an ester group, an alkylene group, and an arylene group, and m represents an integer of 2 to 4, and wherein the polymeric unit represented by --C-- is derived from ethylene, propylene, butene-1, isobutene, styrene, .alpha.-methylstyrene, vinyltoluene, acrylic acid, methacrylic acid, a monoethylenically unsaturated ester of a fatty acid, an ethylenically unsaturated monocarboxylic acid or dicarboxylic acid ester, a monoethylenically unsaturated compound, or a diene;
- and wherein the base support is paper.
