Abstract
The present invention provides a photographic element comprises a support, at least one hydrophilic light-sensitive layer, and a light-insensitive layer containing a binder and polymer matte particles having the formula: EQU (A).sub.x (B).sub.y (C).sub.z (I) where A is a monofunctional ethylenically unsaturated monomer which forms a homopolymer with a Tg less than 20.degree. C., B is a monofunctional ethylenically unsaturated monomer which forms a homopolymer with a Tg greater than 60.degree. C., C is a monomer with two or more ethylenically unsaturated groups, x is about 10 to 95 mole %, y is less than 85 mole %, and z is about 5 to 90 mole %.
