LIGHT TO HEAT CONVERSION LAYER, METHOD FOR PRODUCING SAME, AND DONOR SHEET USING SAID LIGHT TO HEAT CONVERSION LAYER

摘要

Provided are: a light to heat conversion layer which has visible light permeability, excellent near infrared absorption characteristics, and which can improve the transfer accuracy of an organic electroluminescent element using laser irradiation; and a donor sheet using said light to heat conversion layer. The light to heat conversion layer contains near infrared absorption particles and a binder component. The near infrared absorption particles are composite tungsten oxide microparticles wherein if the value for the XRD peak intensity of the (220) face of a silicon powder standard sample (manufactured by NIST, 640c) is defined as 1, the value for the ratio of XRD peak top intensity is at least 0.13, and the light transmissivity is at least 45%.
