Uv light-absorbing skin-protecting composition

An UV light-absorbing skin-protecting composition which comprises an acrylic copolymer comprising the monomer units (A) a compound of the formula: X-Y--CH₂ wherein R¹ is a hydrogen atom or a methyl group, X is a group of the formula: in which R² is a hydroxy group, R³ is a hydrogen atom or hydroxy group, R⁴ and R⁵ are the same or different and a hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a nitro group, a carboxyl group, a sulfonic acid group or a sulfonamide group and R⁶ is a single bond or a methylene group, Y is -O-, -NH- or a group of the formula: in which R⁷ is a hydrogen atom or a lower alkyl group, R⁸ is a hydrogen atom or a hydroxy group, and m and n are the same or different and each 0 or 1, (B) 40 to 75 % by weight of an alkyl acrylate, (C) 10 to 40 % by weight of an alkyl meth­acrylate, and (D) 5 to 30 % by weight of a monoethylenically unsaturated monomer having a carboxyl group; and a medium.
