Provided are: a partial hydrolysis condensation product of hydrolyzable silane compounds; an ink-repellent agent that can selectively provide excellent ink repellency to the upper surface of a partition wall; a negative-type photosensitive resin composition that can selectively provide excellent ink repellency to the upper surface of a partition wall even with low light exposure, and that is less likely to leave an ink-repellent agent inside a dot; a cured film and a partition wall that can maintain excellent ink repellency even after undergoing a UV/O3 irradiation treatment; and an optical element in which ink can be uniformly applied in a dot. Disclosed is a partial hydrolysis condensation product of a mixture comprising: a first hydrolyzable silane compound including a hydrolyzable group and a fluoroalkylene group and/or a fluoroalkyl group, and not including a mercapto group; and a second hydrolyzable silane compound including a mercapto group and a hydrolyzable group, and not including a fluoroalkylene group and a fluoroalkyl group. |
