Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
48 words
Inscribing composition comprising a solid homogeneous mixture of: a. Polyethylene, and b. A water miscible component selected from the group consisting of polyethyleneglycol, nonionic water soluble waxes, nonionic ethylene adducts of higher fatty acids, and mixtures thereof, and c. Wax, and d. Color Pigment, and e. Filler material.
Claim 2
Dependent Claim
48 words
Inscribing composition comprising a solid homogeneous mixture of: a. Polyethylene, and b. A water miscible component selected from the group consisting of polyethyleneglycol, nonionic water soluble waxes, nonionic ethylene adducts of higher fatty acids, and mixtures thereof, and c. Wax, and d. Color Pigment, and e. Filler material.
Claim 3
Dependent Claim
11 words
Composition according to claim 1, wherein high pressure polyethylene is employed.
Claim 4
Dependent Claim
63 words
Composition according to claim 1, wherein the constituents are employed in parts by weight based on the total composition in weight as follows; constituent (a) about 0.5 to 60 parts, constituent (b) about 0.5 to 80 parts constituent (c) about 1 to 40 parts, the parts of color pigment and filler material being between about 1 to 30 and 0.5 to 50, respectively.
Claim 5
Dependent Claim
70 words
Method for preparing a solid homogeneous inscribing composition comprising the steps of admixing polyethylene, a water miscible component selected from the group consisting of polyethyleneglycol, nonionic water soluble waxes, nonionic ethylene adducts of higher fatty acids, and mixtures thereof, wax, color pigment, and filler material at temperature conditions sufficient to soften thermoplastic constituents, homogenizing the mixture thus formed, shaping said mixture and hardening said mixture to form a solid composition.
Claim 6
Dependent Claim
70 words
