US 6,548,150 B1 · Medium for ink-jet recording

Abstract

A recording medium for ink jet printers having superior recording properties for ink jet printers and having superior surface strength in which recorded images are not easily peeled. Acrylic type copolymer in which at least three components of an A component: (metha)acrylate; a B component: hydroxyalkyl (metha)acrylate; and a C component: antioxidation monomer and/or ultraviolet ray absorptivity monomer are copolymerizing components is contained in a coating solution, an ink receiving layer is provided by coating this solution on a base material, whereby a recording medium for ink jet printers is formed.
