    Abstract: PROBLEM TO BE SOLVED: To provide a new type cosmetic or dermatological composition for protecting the skin, having improved stability and good formulation characteristics and also exhibiting good functional characteristics and high sunburn preventive factor. SOLUTION: This composition as the subject sunscreen preparation comprises (A) a copolymer and (B) an inorganic UV filter; wherein the copolymer A is such as to be obtained by (i) free radical solution polymerization of a monomer mixture comprising (a) 0.01-99.99 wt.% of a monomer selected from the group consisting of N-vinylimidazoles and diallylamines, (b) 0.01-99.99 wt.% of a neutral or basic water-soluble monomer, (c) 0-50 wt.% of an unsaturated acid (anhydride), (d) 0-50 wt.% of a free radical-copolymerizable monomer differing from the components (a), (b) and (c), and (e) 0-10 wt.% of a monomer acting as a crosslinking agent and having at least ethylenically unsaturated nonconjugated double bonds, and (ii) partially or wholly quaternizing or protonating the resultant polymer.
