Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
An improved surface coating composition comprising a binder selected from the group consisting of alkyd resins and acrylic resins, and about 0.1 to 5.0 percent by weight of the composition of an antimicrobially active compound having the structural formula ##STR3## wherein R 1 and R 2 each represent an alkyl group having 1 to 8 carbon atoms to inhibit the growth of microorganisms on the dry film formed from said coating composition.
Claim 2
Dependent Claim
72 words
An improved surface coating composition comprising a binder selected from the group consisting of alkyd resins and acrylic resins, and about 0.1 to 5.0 percent by weight of the composition of an antimicrobially active compound having the structural formula ##STR3## wherein R 1 and R 2 each represent an alkyl group having 1 to 8 carbon atoms to inhibit the growth of microorganisms on the dry film formed from said coating composition.
Claim 3
Dependent Claim
14 words
A coating composition according to claim 1 wherein the antimicrobially active compound is 2,5-bis(butylthio)-1,3,4-thiadiazole.
Claim 4
Dependent Claim
14 words
A coating composition according to claim 1 wherein the antimicrobially active compound is 2,5-bis(pentylthio)-1,3,4-thiadiazole.
Claim 5
Independent Claim
74 words
A method for controlling mold growth on a surface coating composition comprising a film forming binder selected from a group consisting of alkyd resins and acrylic resins, that comprises incorporating in said composition about 0.1 to 5.0 percent by weight, based on the weight of the composition, of an antimicrobially active compound having the structural formula ##STR4## wherein R 1 and R 2 each represent an alkyl group having 1 to 8 carbon atoms.
Claim 6
Independent Claim
74 words
A method for controlling mold growth on a surface coating composition comprising a film forming binder selected from a group consisting of alkyd resins and acrylic resins, that comprises incorporating in said composition about 0.1 to 5.0 percent by weight, based on the weight of the composition, of an antimicrobially active compound having the structural formula ##STR4## wherein R 1 and R 2 each represent an alkyl group having 1 to 8 carbon atoms.
Claim 7
Dependent Claim
13 words
A method according to claim 4 wherein the antimicrobially active compound is 2,5-bis(butylthio)-1,3,4-thiadiazole.
