Abstract:
A photographic paper comprising a base layer having an average surface roughness (Sa) of at least 0.7pm and an outer-most layer comprising a hydrophilic colloid binder and colloidal silica, wherein: (i) the weight ratio of colloidal silica to hydrophilic colloid binder in the outer-most layer is 0.05:1 to 0.28:1; and (ii) the amount of colloidal silica present in the outer-most layer is in the range of 8mg/m2to 280mg/m2. The photographic paper is useful for preparing 'non-noisy' photobooks.
Abstract:
A photographic paper having a print retaining layer including a granular tooth providing ingredient in a binder polymer having a Tg of 30 to 65 °C which is the addition product of from about 30 to about 98 mol percent of an alkylmethacrylate wherein the alkyl group has from 3 to 8 carbon atoms, from a bout 2 to about 10 mol percent of an alkali metal salt of an ethylenically unsaturated sulfonic or carboxylic acid, from 0 to about 65 mol percent of a vinyl benzene monomer and from 0 to about 5 mol percent of a crosslinking agent containing two ethylenically unsaturated bonds.
Abstract:
A photographic paper comprising an outer-most layer comprising a hydrophilic colloid binder and colloidal silica, wherein : (i) the weight ratio of colloidal silica to hydrophilic colloid binder in said layer is 0.3:1 to 3:1; and (ii) the colloidal silica has a mean particle size of 2 to 10 nm. The photographic papers have low stickiness rendering them suitable for storage before use and also after use in album-books where the photographic papers are in face-to-face contact.
Abstract:
A photographic imaging element comprising a support having on a front side thereof a silver halide imaging layer and an outermost protective overcoat layer comprising a film-forming binder, and on the backside thereof an outermost protective backcoat layer comprising a film-forming binder; the protective overcoat and backcoat layers each comprising a lubricant present in an amount of at least 5 mg/m 2 and permanent matting agent having a T g of at least 40 °C and an average particle size of from 0.5 to 3 micrometers; and at least one of the protective overcoat layer or the protective backcoat layer further comprising crosslinked elastomeric polymer matte particles that have a T g of 20 °C or less and an average particle size of at least 90 % of or greater than that of the permanent matting agent particles in an amount which is less than the total level of permanent matting agent particles.
