Title (EN) AQUEOUS COATING COMPOSITION
(FR) COMPOSITION DE REVÊTEMENT AQUEUX
Abstract:
(EN) Provided is an aqueous coating composition comprising: (A) an emulsion polymer comprising, structural units of a polymerizable surfactant having the structure of formula (I), wherein R 1 is a phenyl group or a phenyl substituted alkyl group; m1 is 1, 2, 3 or 4; R 2 is an alkyl or a substituted alkyl; m2 is 0 or 1; R 3 is hydrogen or a C 1-C 20 alkyl group; R 4 is hydrogen or a C 1-C 20 alkyl group; represents an alkylene group or a substituted alkylene group, having 2 to 4 carbon atoms; n is an integer in the range of from 1 to 100; and X represents hydrogen or an anionic hydrophilic group selected from - (CH 2) a-SO 3M, - (CH 2) b-COOM, -PO 3M 2, -P (Z)O 2M, or -CO-CH 2-CH (SO 3M) -COOM, wherein a and b are each independently an integer of from 0 to 4, Z represents a residual obtained by removing X from the general formula (I), and each M represents hydrogen, an alkali metal atom, an alkaline earth metal atom, an ammonium residue, or an alkanolamine residue; (B) a wax emulsion in an amount of from 1.1%to 20%by solids weight, based on the dry weight of the emulsion polymer; and (C) a pigment; wherein the aqueous coating composition has a pigment volume concentration of from 56%to 70%. The aqueous coating composition provides a high pigment volume concentration(PVC), improved beading effect and good stain resistance.
(FR) La présente invention concerne une composition de revêtement aqueux comprenant : (A) un polymère en émulsion comprenant, des motifs structurels d’un tensioactif polymérisable ayant la structure de formule (I), R1 est un groupe phényle ou un groupe alkyle substitué par un groupe phényle ; m1 a la valeur de 1, 2, 3 ou 4 ; R2 est un groupe alkyle ou un groupe alkyle substitué ; m2 a la valeur de 0 ou 1 ; R3 est un atome d’hydrogène ou un groupe alkyle en C1 à C20 ; R4 est un atome d’hydrogène ou un groupe alkyle en C1 à C20 ; [A] représente un groupe alcylène ou un groupe alcylène substitué, ayant de 2 à 4 atomes de carbone ; n est un nombre entier d’une valeur située dans la plage de 1 à 100 ; et X représente un atome d’hydrogène ou un groupe hydrophile anionique sélectionné parmi -(CH2)a-SO3M, -(CH2)b-COOM, -PO3M2, -P(Z)O2M, ou -CO-CH2-CH(SO3M)-COOM, a et b sont chacun indépendamment un nombre entier d’une valeur de 0 à 4, Z représente un résidu obtenu par élimination de X de la formule générale (I), et chaque M représente un atome d’hydrogène, un atome de métal alcalin, un atome de métal alcalino-terreux, un résidu ammonium, ou un résidu alcanolamine ; (B) une émulsion de cire en une quantité de 1,1 % à 20 % en poids de matières solides, sur la base du poids sec du polymère en émulsion ; et (C) un pigment ; la composition de revêtement aqueux présente une concentration de pigment en volume de 56 % à 70 %. La composition de revêtement aqueux fournit une concentration élevée en volume de pigment (PVC), un effet perlant amélioré et une bonne résistance aux taches.
