Abstract
The present invention relates to a composition composed of a crosslinkable resin containing lactam groups; a DMAPMA/HEMA copolymer copolymer; and a cellulose based water absorbent polymer. The invention also relates to a printable substrate composed of a substrate, optionally, a layer serving as a base layer; and at least one layer derived from a composition as defined in the present invention. Process for preparing such a printable substrate is also provided.

A composition comprising:
- a crosslinkable resin comprising lactam groups;
- a DMAPMA/HEMA copolymer;
- and
- a cellulose based water absorbent polymer.
A printable substrate comprising:
- a substrate;
- optionally, a layer serving as a base layer;
- and
- at least one layer derived from a composition comprising:
- a crosslinkable resin comprising lactam groups;
- a DMAPMA/HEMA copolymer;
- and
- a cellulose based water absorbent polymer.
A photographic paper comprising:
- a base paper;
- optionally a layer serving as a base layer;
- and
- at least one layer derived from the composition comprising:
- a crosslinkable resin comprising lactam groups;
- a DMAPMA/HEMA copolymer;
- and
- a cellulose based water absorbent polymer.
A process for preparing a printable substrate comprising the steps of:
- a) providing a substrate,
- b) optionally applying on the substrate a layer serving as a base layer,
- c) applying, on the substrate or the base layer, at least one layer of a composition comprising:
- a crosslinkable resin comprising lactam groups,
- a DMAPMA/HEMA copolymer, and
- a cellulose based water absorbent polymer.
A process for preparing a photographic paper comprising the steps of:
- a) providing a base paper,
- b) optionally applying on the base paper a layer serving as a base layer,
- c) applying, on the base paper or the base layer, at least one layer of a composition comprising:
- a crosslinkable resin comprising lactam groups,
- a DMAPMA/HEMA copolymer, and
- a cellulose based water absorbent polymer, and
- d) calendering the base paper obtained in step (c).
