## Abstract

A water-dispersed coating composition comprising an amino resin, and a dispersion of latex polymer particles comprising from 0.1 to 2 weight percent of a multi-ethylenically unsaturated monomer and from 0.1 to 2 weight percent of (meth)acrylamide.

## Claims

### Claim 1

A water-dispersed coating composition comprising
a) at least one aqueous dispersion of particles of a copolymer made from, based on the weight of the copolymer:
i from 96 to 99.8 weight percent of at least one monoethylenically unsaturated nonionic monomer not including the (meth)acrylamide of component iii;
ii from 0.1 to 2 weight percent of a multi-ethylenically unsaturated monomer comprising allyl (meth)acrylate;
iii from 0.1 to 2 weight percent of (meth)acrylamide;
wherein the said copolymer comprises no more than 1 weight percent, based on the weight of the copolymer, of a self-crosslinking monomer; and
b) at least one amino resin selected from the group consisting of melamine/formaldehyde resin, urea/formaldehyde resin, guanamine/formaldehyde resin, benzoguanamine/formaldehyde resin and acetoguanamine/formaldehyde resin or combinations thereof;
wherein the ratio of components a:b is from 1:99 to 20:80 based on the solids of both components.

### Claim 2 (depends on 1)

The composition of claim 1 wherein the said copolymer further comprises from 0.1 to 2 weight percent of one or more acid functional monomer.

### Claim 3 (depends on 1)

The composition of claim 1 further comprising N,N-dimethylaminoethyl (meth)acrylate, N,N-dimethylaminopropyl (meth)acrylamide, N-vinyl pyrrolidinone, or hydroxyethyl (meth)acrylate, or combinations thereof.

### Claim 4 (depends on 1)

The composition of claim 1 wherein the said copolymer comprises no more than 1 weight percent, based on the weight of the copolymer, of polymerized units of monomers comprising N-methylol groups.

### Claim 5 (depends on 1)

The composition of claim 1 wherein the said copolymer comprises no more than 0.5 weight percent, based on the weight of the copolymer, of a self-crosslinking monomer.

### Claim 6 (depends on 1)

The composition of claim 1 wherein the said copolymer does not comprise a self-crosslinking monomer.

### Claim 7

A method for treating a glass fiber non-woven comprising:
(a) forming an aqueous admixture by admixing with water, or one or more aqueous solvent, and an amino resin, from 1% to 25% by weight, based on the weight of solids of said amino resin, of at least one aqueous dispersion of particles made from a copolymer, based on the weight of the copolymer, comprising:
i. from 96 to 99.8 weight percent of at least one monoethylenically unsaturated nonionic monomer not including the (meth)acrylamide of component iii;
ii. from 0.1 to 2 weight percent of a multi-ethylenically unsaturated monomer comprising allyl (meth)acrylate;
iii. from 0.1 to 2 weight percent of (meth)acrylamide; wherein the said copolymer comprises no more than 1 weight percent, based on the weight of the copolymer, of a self-crosslinking monomer; and
(b) contacting said glass fiber non-woven with said aqueous admixture or, alternatively, applying said aqueous admixture to the glass fiber non-woven; and
(c) heating said admixture at a temperature of from 100 C to 400 C.

### Claim 8 (depends on 1)

The composition of claim 1 wherein the said copolymer in dispersion (a) comprises the copolymerization product of from 0.1 to 2 wt. %, based on the weight of the copolymer, of one or more mono-ethylenically unsaturated acid functional monomer.
