A donor sheet for transferring an image pattern to an image receiving element by a thermal imaging process using laser beam, comprising a base having formed in order on the base a light-to-heat conversion layer, and a transfer layer containing an image component which is melted by heating due to an action of the light-to-heat conversion layer and transferred to the image receiving element in a patterned form, in which the image component of the transfer layer contains an ink-repellent or solvent-repellent compound in an optimized amount. Using the donor sheet, it becomes possible to produce an separation member such as partition pattern and black matrix of a color filter by a shortened manufacturing step with ease and accuracy at high contrast, and can impart excellent ink repellency to the separation member.
