HOT MELT INK COMPOSITION, METHOD FOR PREPARING A HOT MELT INK COMPOSITION AND USE OF A HOT MELT INK COMPOSITION

摘要

The invention relates to a hot melt ink composition, the hot melt ink composition being solid at room temperature and in a liquid state at an elevated temperature, comprising a binder, a colorant, a crystalline material, and a crystallization retardant, wherein the crystalline material is a di-substituted compound and the crystallization retardant is a mono-substituted derivative of the crystalline material. The invention further relates to a method for preparing such hot melt compositions and to use of a hot melt ink composition.

1. A hot melt ink composition; the hot melt ink composition being solid at room temperature and in a liquid state at an elevated temperature, comprising a binder, a colorant, a crystalline material, and a crystallization retardant, wherein the crystalline material is a di-substituted compound and the crystallization retardant is a mono-substituted derivative of the crystalline-material
wherein the crystalline material is a component having the following general formula: wherein: R2 is a C1-12 linear alkane diyl or a C5-12 alkane diyl containing a cyclic group B1 and B2 may be the same or different and are both selected from the group of —C(O)O, —OC(O)—, —C(O)N(H)—, —N(H)C(O)— and —O—; where R1 and R−2 are the same or different and are selected from a C1-8 alkyl or a C1-8 alkoxy group, and n and m are the same or different and are equal to 0, 1, 2 or 3 .
