Abstract: The present invention provides an erasable colored pencil lead composition comprising a colorant, one or more binder resins, a fibrillatable or fibrillated material, and a filler. The colored pencil lead of the present invention produces marks on paper, which are easily erased by ordinary pencil eraser. The mark made using the composition has a cohesive nature that assists in the removal from paper in sheet or film like sections by the use of an ordinary eraser without smearing or leaving a residue. In a preferred embodiment, the composition is free or substantially free of low melting waxes or wax like materials. Examples of suitable binder resins include high density polyethylene, low density polyethylene, polypropylene, and high melting waxes. Examples of fibrillated or fibrillatable materials include fibrillatable or fibrillated polytetrafluoroethylene and ethylene-vinyl acetate copolymer. The colored pencil lead composition may further include a lubricant.

Abstract: A marking system that advantageously minimizes messiness during use is disclosed. The marking system comprises a marking composition comprising at least one color precursor in the form of a leuco dye. A marking instrument can be utilized to store the marking composition and/or apply the marking composition to a desired substrate. The substrate is provided with a coating comprising at least one color-triggering developer. Upon application of the leuco dye to the substrate, a chromophore, and hence, color, is formed. If, however, color is inadvertently triggered on an unintended surface, thereby resulting in an unwanted stain, the stain can be readily removed.

Abstract: A multi-purpose easel is provided for use by children, artists, and the like.
