(57) Abstract: A novel photodegradable silane coupling agent containing a silane compound having an amino group, a novel silane compound having an amino group, and a silane compound having an amino group. Provided is a substrate treated with a novel photodegradable silane coupling agent and a method for producing the same. SOLUTION: A silane compound in which an amino group or the like is protected by a photodegradable protecting group, for example, a compound represented by the following general formula [1] X represents an alkoxy group or a halogen atom, Y represents a photodegradable protective group, and R 1 represents an alkyl group. m is 0-3 And n represents an integer. ), Preferably represented by the general formula [2] (in the general formula [2], R 2 represents a hydrogen atom or an alkyl group, and R 3 and R 4 each independently represent a hydrogen atom or an alkoxy group). A photodegradable silane coupling agent containing a silane compound is prepared. Embedded image Embedded image |
