Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A scuff-masking composition for glass articles which comprises, in solution if solvent is present: Component A which is an organopolysiloxane represented by the average compositional formula ##EQU4## wherein R is an alkyl group having 1 to 4 carbon atoms, and x, y and z are the numbers having the relationship ≦ x+y<2 1<y/x<10 0.4≦z<2; Component B which is a curing catalyst for component A; and Component C which is a surfactant, the quantity of the surfactant being in amounts sufficient to improve removability of the cured product by aqueous alkali said composition being curable at up to about 50° C.
Claim 2
Dependent Claim
100 words
A scuff-masking composition for glass articles which comprises, in solution if solvent is present: Component A which is an organopolysiloxane represented by the average compositional formula ##EQU4## wherein R is an alkyl group having 1 to 4 carbon atoms, and x, y and z are the numbers having the relationship ≦ x+y<2 1<y/x<10 0.4≦z<2; Component B which is a curing catalyst for component A; and Component C which is a surfactant, the quantity of the surfactant being in amounts sufficient to improve removability of the cured product by aqueous alkali said composition being curable at up to about 50° C.
Claim 3
Dependent Claim
20 words
The composition as set forth in claim 1, in which the composition is in the form of an alcohol solution.
Claim 4
Independent Claim
130 words
A method of masking scuffs on glass articles, which comprises coating the scuffed part of the glass article with an organopolysiloxane composition and curing the composition at a temperature up to about 50° C., said composition comprising, in solution if the solvent is present: Component A which is an organopolysiloxane represented by the average compositional formula ##EQU5## wherein R is an alkyl group having 1 to 4 carbon atoms, and x, y and z are the numbers bearing the relationship ≦ x+y<2 1<y/x<10 0.4≦z<2; Component B which is a curing catalyst for component A; and Component C which is a surfactant, the quantity of the surfactant being in amounts sufficient to improve removability of the cured product by aqueous alkali, said composition being curable at up to about 50° C.
Claim 5
Independent Claim
130 words
A method of masking scuffs on glass articles, which comprises coating the scuffed part of the glass article with an organopolysiloxane composition and curing the composition at a temperature up to about 50° C., said composition comprising, in solution if the solvent is present: Component A which is an organopolysiloxane represented by the average compositional formula ##EQU5## wherein R is an alkyl group having 1 to 4 carbon atoms, and x, y and z are the numbers bearing the relationship ≦ x+y<2 1<y/x<10 0.4≦z<2; Component B which is a curing catalyst for component A; and Component C which is a surfactant, the quantity of the surfactant being in amounts sufficient to improve removability of the cured product by aqueous alkali, said composition being curable at up to about 50° C.
Claim 6
Dependent Claim
20 words
The method as set forth in claim 3, in which the composition is in the form of an alcohol solution.
Claim 7
Dependent Claim
37 words
The glass article which has a coat film on at least a part of its surface thereby masking scuffs on the surface, the film being a cured product of the composition claimed in claim 1 or 2.
Claim 8
Dependent Claim
22 words
The composition as set forth in claim 1 or 2, in which the surfactant is selected from the group of nonionic surfactants.
Claim 9
Dependent Claim
42 words
The composition as set forth in claim 1 or 2, in which the surfactant is a nonionic surfactant selected from the group consisting of propylene glycol fatty acid esters, glycerine fatty acid esters, sorbitan fatty acid esters, and sucrose fatty acid esters.
Claim 10
Dependent Claim
22 words
The method as set forth in claim 3 or 4, in which the surfactant is selected from the group of nonionic surfactants.
Claim 11
Dependent Claim
42 words
The method as set forth in claim 3 or 4, in which the surfactant is a nonionic surfactant selected from the group consisting of propylene glycol fatty acid esters, glycerine fatty acid esters, sorbitan fatty acid esters, and sucrose fatty acid esters.
