Hydrophilic acrylic copolymers, hydrophilic acrylic resin particles and ink-jet recording media

The acrylic copolymer and the acrylic resin particles of the invention have a recurring unit derived from a nitrogen-containing acrylic monomer having, in its molecule, at least one CH2=CR1-CO- group (R1 is a hydrogen atom, methyl or ethyl) and at least one -N+R23.X- group (R2 is H-, an alkyl group...

More Information
Summary:The acrylic copolymer and the acrylic resin particles of the invention have a recurring unit derived from a nitrogen-containing acrylic monomer having, in its molecule, at least one CH2=CR1-CO- group (R1 is a hydrogen atom, methyl or ethyl) and at least one -N+R23.X- group (R2 is H-, an alkyl group of 1 to 5 carbon atoms or an alkylol group of 1 to 5 carbon atoms, and X is a halogen atom) and a recurring unit derived from an acrylic monomer represented by the formula CH2=CR3-CO-Q wherein R3 is H-, CH3- or C2H5-, and Q is -NH2, -NH-R4-OH (R4 is an alkylene group of 1 to 5 carbon atoms) or -R5 (R5 is H- or an alkoxy group of 1 to 20 carbon atoms), and further have a crosslinked structure. The ink-jet recording medium of the invention contains the acrylic resin particles in its ink-receiving layer. The acrylic resin particles have good water resistance though they are hydrophilic. Therefore, the resin particles are favorable as those introduced into an ink-receiving layer of an ink-jet recording medium.
