US Patent 7811643 Inkjet recording sheet

Provided is an inkjet recording sheet. The inkjet recording sheet includes a support film comprising homopolypropylene, a propylene-ethylene random copolymer, a propylene-ethylene block copolymer, high-density polyethylene, and polystyrene, a primer layer having larger elongation than the support film and comprising a hydroxyl group-containing polyolefin resin, and an ink absorbing layer. The inkjet recording sheet has substantially the same texture as real photo paper and excellent image quality. When a matte-finish surface is used as a recording surface, a non-glossy treatment effect can be obtained. Therefore, various kinds of consumer's desires can be satisfied. In addition, since the inkjet recording sheet has an appropriate stiffness range, no paper jamming occurs upon continuous printing, substantially the same texture as real photo paper and excellent image quality are ensured. Further, when a matte-finish surface is used as a recording surface, a non-glossy treatment effect can be obtained even when a separate matte paper is not used. In this way, diverse change in an image texture enables to satisfy various kinds of consumer's desires without additional increase of a manufacturing cost.
