Abstract: The present invention provides a photosensitive resin composition comprising a component (a): a siloxane resin obtained by hydrolyzing and condensing a silane compound comprising a compound represented by the general formula (1) shown below, a component (b): a solvent dissolving the component (a) therein, and a component (c): a quinonediazide sulfonic acid ester. wherein R1 represents an organic group; A represents a divalent organic group; and X represents a hydrolyzable group, wherein plural X groups in one molecule may be the same or different.

Abstract: The photosensitive resin composition of the invention comprises component (a): a first siloxane resin obtained by hydrolytic condensation of a first silane compound comprising a compound represented by the following formula (1), component (b): a solvent in which component (a) dissolves, and component (c): an ester of a phenol or alcohol and naphthoquinone diazide sulfonic acid.

Abstract: The image data with the copy-forgery-inhibited pattern image added and an image area flag signal stored in the hard disk drive are inputted into a thinning filter. A thinning circuit does not perform thinning processing on these pieces of data and outputs the inputted image, as it is. The filter performs processing so that an image of a copy-forgery-inhibited pattern background part may be deleted. A selector selects an image signal not passing through the filter for a latent mark of the copy-forgery-inhibited pattern whose image area flag is set as “Character,” and select an image signal subjected to the processing by the filter for a copy-forgery-inhibited pattern background part whose image area flag is set as “Photograph.” By doing so, it is possible to perform low pass processing on only the copy-forgery-inhibited pattern background part and perform processing of making a latent-mark part emerge.
