    Abstract: Disclosed are aqueous dispersions (A), comprising a micronized organic UV filter (a) selected from (a1) the micronized compound of formula (1), wherein R1 and R2 independently from each other are C1-C20alkyl; C2-C20alkenyl; C3-C10ocycloalkyl; C3-C10cycloalkenyl; or R1 and R2 together with the linking nitrogen atom form a 5- or 6-membered heterocyclic ring; A is —N(R3)—; —O—; or the direct bond; B is a bivalent radical selected from alkylene, cycloalkylene alkenylene or phenylene radical which is optionally substituted by a carbonyl- or carboxy group; a radical of formula *—CH2—C≡═C—CH2—; or the divalent radical *-B-* corresponds to the formula (1a), wherein n1 is a number from 1 to 3; A is —N(R3)—; or —O—; and R3 is hydrogen; C1-C5alkyl; or hydroxy-C1-C5alkyl; (a2) the micronized compound of formula (2), wherein T1 is hydrogen; C1-C12alkyl; preferably iso-octyl, or C1-C4alkyl substituted by phenyl; (a3) the micronized compound of formula (3a); wherein R4 and R5 independently from each other are hydrogen; C1-C18alkyl; or C6-C12acryl; R6, R7 and R8 independently from each other, are hydrogen; C1-C18alkyl; or a radical of formula (3b); wherein R9, R10 and R11 independently from each other, are hydrogen; or C1-C18alkyl; (a4) the micronized compound of formula (4); wherein R12 and R13, independently from each other, represent hydrogen; halogen; C1-C12alkyl: C1-C18hydroxy; C1-C18alkoxy; poly(ethoxy)-alkoxy with a C1-C4 alkyl fragment and an ethoxy number ranging from 1 to 4; C1-C4mono- or dialkyl amino, R14 represents halogen; hydroxy; amino; phenyl which is optionally substituted 1 to 3 times by a hydroxy radical situated at least in a para or phenyl position, possibly 1 to 3 times substituted in an ortho, meta or para position by a C1-C12alkoxy or cyano or C1-C7alkyl-amino group; and (b) a vinylpyrrolidone copolymer or homopolymer.
