Abstract
A plastic modified writing or inscribing composition obtained by incorporating plastics of different solvent solubility in the composition is prepared. When applied to a suitable surface, spreading of the composition is accomplished by subsequent solvent treatment.
Claims4
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.
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.
