Abstract
Abstract Surface-coating compositions that have improved resistance to attack by bacteria, fungi, and other microorganisms contain from 0.1% to 3% by weight of a biocidal compound having the structural formula ##STR1## wherein R represents hydrogen or --COR'; R' represents alkyl, aryl, or aralkyl; and X and Y, which may be the same or different, represent hydrogen or chlorine.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
92 words
A surface-coating composition having improved resistance to attack by bacteria, fungi, and other microorganisms that comprises (a) a water-insoluble resinous binder selected from the group consisting of synthetic linear addition polymers prepared by the emulsion polymerization of ethylenically-unsaturated monomers, oleoresinous binders, and mixtures thereof and (b) 0.1% to 3%, based on the weight of the composition, of a biocidal compound having the structural formula ##STR4## wherein R represents hydrogen or --COR'; R' represents alkyl, aryl, or aralkyl; and X and Y, which may be the same or different, represent hydrogen or chlorine.
Claim 2
Dependent Claim
92 words
A surface-coating composition having improved resistance to attack by bacteria, fungi, and other microorganisms that comprises (a) a water-insoluble resinous binder selected from the group consisting of synthetic linear addition polymers prepared by the emulsion polymerization of ethylenically-unsaturated monomers, oleoresinous binders, and mixtures thereof and (b) 0.1% to 3%, based on the weight of the composition, of a biocidal compound having the structural formula ##STR4## wherein R represents hydrogen or --COR'; R' represents alkyl, aryl, or aralkyl; and X and Y, which may be the same or different, represent hydrogen or chlorine.
Claim 3
Dependent Claim
25 words
A surface-coating composition as set forth in claim 1 that contains 1% to 2%, based on the weight of the composition, of said biocidal compound.
Claim 4
Dependent Claim
24 words
A surface-coating composition as set forth in claim 1 wherein the biocidal compound has the structural formula ##STR5## wherein R has the aforementioned significance.
Claim 5
Dependent Claim
15 words

Claim 9
Independent Claim
97 words
The method of controlling the growth of bacteria, fungi, and other microorganisms in a surface-coating composition that contains a water-insoluble resinous binder selected from the group consisting of synthetic linear addition polymers prepared by the emulsion polymerization of ethylenically-unsaturated monomers, oleoresinous binders, and mixtures thereof that comprises incorporating in said composition 0.1% to 3%, based on the weight of said composition, of a biocidal compound having the structural formula ##STR6## wherein R represents hydrogen or --COR'; R' represents alkyl, aryl, or aralkyl; and X and Y, which may be the same or different, represent hydrogen or chlorine.
Claim 10
Independent Claim
97 words
The method of controlling the growth of bacteria, fungi, and other microorganisms in a surface-coating composition that contains a water-insoluble resinous binder selected from the group consisting of synthetic linear addition polymers prepared by the emulsion polymerization of ethylenically-unsaturated monomers, oleoresinous binders, and mixtures thereof that comprises incorporating in said composition 0.1% to 3%, based on the weight of said composition, of a biocidal compound having the structural formula ##STR6## wherein R represents hydrogen or --COR'; R' represents alkyl, aryl, or aralkyl; and X and Y, which may be the same or different, represent hydrogen or chlorine.
Claim 11
Dependent Claim
20 words
The method of claim 8 wherein the biocidal compound has the structural formula ##STR7## wherein R has the aforementioned significance.
Claim 12
Dependent Claim
