Composition for color Erasable Pencil Mines, method to delete a Mark made by the composition and Process for preparing such a mine of Pencil.

摘要

A composition for Mines, which comprises a pencil color Erasable Dye, one or more Binder Resins, one or more fibrilable fibrillated material and filler.The pencil of the present Invention produces color marks on unpape l which are easily Erased by an Eraser lu00e1pizcomun.The Mark using the composition has a Cohesive Nature that facilitates its role in Removal of sections similar to sheet or Film through the use of a gomacomun s in Stain or dLeave a residue. In a Preferred embodiment, the composition is free or substantially free of Wax or similar material below Melting Point to waxes.Examples of suitable Binders include polyethylene High densid ad densidadpolipropileno Waxes, Polyethylene of low and High Melting Point.Examples of the materials include fibrilables or fibrillated polytetrafluoroethylene or in the form depequenas fibrillated Fibers and Copolymer of ethylene and Vinyl acetatode.Composition For Colored Pencil Mines can further include a LUBRICANT.Examples include appropriate Lubricants Lubricants in Particulate form such as PTFE Micronized and Lubricants that are not in the form of partu00edculastales comomaterial is alcoxilados,For example, Polyethylene glycols. A process for using the composition for Mines of Crayons. A process for the lapreparacion color pencil of the present Invention.
