  • Publication number: 20050233547
    Abstract: Provided is a laminated body (1) comprising a substrate (2) to be ground and a support (5), where the substrate (2) is ground to a very small thickness and can then be separated from the support (5) without damaging the substrate (2). One embodiment of the present invention is a laminated body (1) comprising a substrate (2) to be ground, a joining layer (3) in contact with the substrate (2) to be ground, a photothermal conversion layer (4) comprising a light absorbing agent and a heat decomposable resin, and a light transmitting support (5). After grinding the substrate surface which is opposite that in contact with the joining layer (3), the laminated body (1) is irradiated through the light transmitting support (5) and the photothermal conversion layer (4) decomposes to separate the substrate (2) and the light transmitting support (5).

  • Publication number: 20050157157
    Abstract: 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.
