Abstract
Abstract A water-dispersed resin composition obtained by dispersing in water a neutralized resin prepared by neutralizing a part or whole of the carboxyl groups in an alkyd resin produced by reacting (A) an oil or fatty acid, (B) tris(2-hydroxyethyl)isocyanurate and/or tris(hydroxymethyl)isocyanurate, (C) a polyhydric alcohol, (D) a monobasic acid, (E) a polybasic acid and (F) polyethylene glycol, wherein individual components (A) to (F) are formulated in terms of the ratio of the number of hydroxyl groups/the number of carboxyl groups in the range of 1.0/1 to 1.6/1 and said alkyd resin has an acid value of 30 or less, is excellent in drying properties and in film properties such as gloss, water resistance, etc.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
A water-dispersed resin composition comprising (i) water and (ii) a neutralized resin dispersed in water prepared by neutralizing a part or whole of the carboxyl groups in an alkyd resin produced by reacting (A) 0 to 60% by weight of one or more oils or fatty acids, (B) 10 to 60% by weight of tris(2-hydroxyethyl)isocyanurate and/or tris(hydroxymethyl)isocyanurate as a trihydric alcohol, (C) 0 to 50% by weight of one or more polyhydric alcohols having 2 to 6 hydroxyl groups in a molecule except for the component (B), (D) 0 to 20% by weight of one or more monobasic acids having 6 to 18 carbon atoms in a molecule except for the component (A), (E) 10 to 50% by weight of one or more polybasic acids having 4 to 10 carbon atoms in a molecule or acid anhydrides thereof, and (F) 2 to 15% by weight of polyoxyethylene glycol having a molecular weight of 600 to 20,000, wherein individual components are formulated in terms of the ratio of the number of hydroxyl groups/the number of carboxyl groups in the range of 1.0/l to 1.6/l, and said alkyd resin has an acid value of 30 or less.
Claim 2
Dependent Claim
195 words
A water-dispersed resin composition comprising (i) water and (ii) a neutralized resin dispersed in water prepared by neutralizing a part or whole of the carboxyl groups in an alkyd resin produced by reacting (A) 0 to 60% by weight of one or more oils or fatty acids, (B) 10 to 60% by weight of tris(2-hydroxyethyl)isocyanurate and/or tris(hydroxymethyl)isocyanurate as a trihydric alcohol, (C) 0 to 50% by weight of one or more polyhydric alcohols having 2 to 6 hydroxyl groups in a molecule except for the component (B), (D) 0 to 20% by weight of one or more monobasic acids having 6 to 18 carbon atoms in a molecule except for the component (A), (E) 10 to 50% by weight of one or more polybasic acids having 4 to 10 carbon atoms in a molecule or acid anhydrides thereof, and (F) 2 to 15% by weight of polyoxyethylene glycol having a molecular weight of 600 to 20,000, wherein individual components are formulated in terms of the ratio of the number of hydroxyl groups/the number of carboxyl groups in the range of 1.0/l to 1.6/l, and said alkyd resin has an acid value of 30 or less.
