Abstract
A recording medium for ink jet printers having superior effects in preventing recorded image deterioration such as lowering of image clarity, decrease in density, change in color tone, etc., under high temperature and high humidity, is provided. An ink receiving layer is formed on a base material by coating acrylic copolymer containing at least (meth)acrylate having a solubility parameter (δ) of 15.0 to 23.0 MPa½ as a copolymerizing component, and thereby a recording medium for ink jet printers is produced.
Claims8
A recording medium for ink jet printers comprising an ink receiving layer provided on a base material, wherein the ink receiving layer contains acrylic copolymer in which at least (meth)acrylate having a solubility parameter (δ) of 15.0 to 23.0 MPa½ is a copolymerizing component and an ester group in the (meth)acrylate is a cycloalkyl group, and the acrylic copolymer consists of at least four copolymerizing components of an (a) component:
- (meth)acrylate having a solubility parameter (δ) of 15.0 to 23.0 MPa½, a (b) component:
- dialkylaminoalkyl (meth)acrylate, and a (c) component:
- acrylamide, and a (d) component:
- alkoxy polyethylene glycol (meth)acrylate.
