The present invention relates to a heat-sensitive recording material, wherein the color layer contains at least one removable dye, more particularly a dye that can be removed in the waste paper cycle; to a process for decoloring a heat-sensitive recording material in order to obtain a fibrous material mixture, comprising the steps of providing a mixture of the heat-sensitive recording material and at least one other paper type, more particularly at least one waste paper type, and subsequently decoloring the mixture in a deinking process in order to obtain a fibrous material mixture; to a fibrous material mixture obtained by means of said process; to a process for producing a recycled paper comprising the fibrous material mixture by compressing and dewatering the fibrous material mixture; and to a recycled paper which can be obtained by means of said process.

The present invention relates to a method of forming an image on a substrate comprising a transparent or translucent composition applied thereto, wherein the transparent or translucent composition comprises a protein in a non-denatured state, and the method comprises applying radiation to the transparent or translucent composition to denature the protein and thereby form an image on the substrate. The invention also relates to a method of preparing a substrate on which an image can be formed, and related substrates, compositions and uses thereof.

This disclosure provides laser markable polymerizable resin compositions comprising infrared absorbing marking additives to achieve improved laser markability of 3-D printed objects obtained from these polymerizable resin composition, and methods for marking the cured resin compositions using an infrared laser.

A laminate is provided and includes a base material; an intermediate layer provided on the base material and having an accommodation part; a recording medium provided in the accommodation part; and an overlay layer provided on the intermediate layer. The accommodation part is provided in a part of a plane of the intermediate layer, and the accommodation part is a through hole penetrating in the thickness direction of the intermediate layer or a recess recessed in the thickness direction of the intermediate layer. The recording medium includes a color development layer containing: a coloring compound having an electron donating property; a developer having an electron accepting property; and a matrix resin. The base material, the intermediate layer, and the overlay layer contain the same type of resin material.

Direct thermal print media comprising side chain crystalline material are disclosed. The print media are substantially free of bis-phenols, and can retain color when subjected to light and/or temperatures ranging from, for example, 15 C. to 45 C. for long durations.

Provided is a thermosensitive recording medium including a support and a thermosensitive recording layer disposed on or above the support. The thermosensitive recording layer include a compound represented by General Formula (1) and a styrene-acryl resin, where, in General Formula (1), R.sub.2 is a C1-12 straight-chain, branched-chain, or alicyclic alkyl group, C7-12 aralkyl group that is substituted with a C1-12 alkyl group, a C1-12 alkoxy group, a C6-12 aryl group or a halogen atom, or a C6-12 aryl group that is unsubstituted or substituted with a C1-12 alkyl group, a C1-12 alkoxy group, a C6-12 aryl group, or a halogen atom, where two or more R.sub.2 may be identical to or different from each other; and A.sub.1 is a hydrogen atom or a C1-4 alkyl group, where two or more A.sub.1, may be identical to or different from each other. ##STR00001##
