Laser thermal transfer ribbon and preparation method thereof

Abstract

The invention belongs to the technical field of thermal transfer printing materials and particularly relates to a laser thermal transfer ribbon. The laser thermal transfer ribbon is formed by a base film, a separating layer, a laser imaging layer and an ink coating layer. Water or alcohol or a mixed solvent is added to a waterborne releasing agent or a resin releasing agent or a waxiness releasing agent to form the separating layer. The laser imaging layer is composed of hydroxyl acrylic resin, celluosic resin, isocyanate, additives and a mixed solvent. The ink coating layer is composed of acrylic resin, chloride ether resin, rosin resin, petroleum resin, pigments, additives and a mixed solvent. The laser thermal transfer ribbon is clear in transferred character and image, good in adhesive force, resistant in friction, poaching-proof, aging-resistant, resistant in high-low temperature, suitable for wide transfer base materials and transfer temperature, and capable of meeting transfer demands of high speed and high efficiency. The laser thermal transfer ribbon enables a product to be bright, colorful, exquisite and gorgeous, improves product levels, has a certain anti-fake function, and improves product market compatibility.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing materials, in particular to a thermal transfer printing ribbon and a manufacturing method thereof. Background technique [0002] As a non-contact printing peripheral output device, thermal transfer printing has become a type of printer with a high market share. Its imaging principle uses heat and pressure to transfer ink from carbon ribbon media to paper or other types of printing media to form text and images. The thermal transfer ribbon is a necessary consumable material for printing, and it is also the core material that determines the quality of the thermal transfer image. The thermal transfer ribbon must ensure that the printed text or pattern will not be affected by external factors, and can be stored for a long time without fading. It will not change color due to high ambient temperature or exposure to solvents. Based on the characteristics of thermal transfer printing t...
