Abstract

Claims18
A method of treating a paper, comprising:
- (a) providing a sheet comprising a paper basestock and having a backside and an inkjet ink-receiving side opposite said backside;
- (b) applying a coating onto said backside, wherein said coating comprises a binder, an anti-curl agent and a polyethylene particle component consisting of first and second portions of polyethylene particles dispersed in said binder, the particles of said first portion being smaller than the particles of said second portion wherein said first and second portions have non-contiguous particle size ranges, and wherein said applying excludes extrusion coating, to produce a paper with a smooth surface having a photobase texture on said backside.
The paper of 17, wherein, in (a), providing said sheet includes:
- (a1) providing a sheet comprising an untreated basestock and having a backside and an ink-receiving side opposite said backside;
- and
- (a2) treating both said ink-receiving side and said backside with a print-enhancing offset coating, to yield a treated basestock prior to performing (b).
