The present disclosure is directed to an aqueous dispersion of polymeric particles having core-shell structure, the preparation thereof and the coating formed therefrom. In the polymeric particles, at least one of the polymeric core and the polymeric shell is formed from a monomers mixture comprising isobornyl (meth)acrylate and wherein the isobornyl (meth)acrylate is present in the monomers mixture in an amount of 1 wt % to 40 wt %, relative to the weight of the corresponding monomers mixture for the polymeric core or the polymeric shell.

Aqueous dispersion of polymeric particles having core-shell structure, the preparation thereof and the coating formed therefrom

The present invention is a water dispersible copolymer for scavenging formaldehyde, the copolymer being based on acrylic copolymer comprising one or more acetoacetyl functional groups and one or more hydrophilic groups chemically bonded to its molecular backbone, wherein the acrylic copolymer has a number average molecular weight of 2000-100,000 g/mol; and wherein the acrylic copolymer comprises between 10 wt % and 30 wt % of the acetoacetyl functional groups relative to the weight of the acrylic copolymer. The present invention also refers to an aqueous dispersion containing said water dispersible copolymer, as well as an article coated by a coating comprising the aqueous dispersion.

Water dispersible copolymers for scavenging formaldehyde

A curable resin composition includes an acetoacetyl functional unsaturated polyester with a branched molecular skeleton containing olefinically unsaturated functional groups therein and acetoacetyl functional groups chemically bonded to the branched molecular skeleton. The acetoacetyl functional unsaturated polyester contains at least 2 wt % of the olefinically unsaturated functional groups, relative to the total weight of the acetoacetyl functional unsaturated polyester, and at least 20 wt % of the acetoacetyl functional groups, relative to the total weight of the acetoacetyl functional unsaturated polyester. The curable resin composition can be used to formulate coating compositions.

Formaldehyde-scavenging coating composition

This disclosure is directed to a self-crosslinkable polymer and and an aqueous dispersion comprising particles of the polymer. The self-crosslinkable polymer has a molecular skeleton containing urethane linkages, and a hydrazide functional group and a carbonyl functional group capable of reacting with the hydrazide functional group chemically bonded to the molecular skeleton.
