The invention provides a decomposable resin composition, which is stable at the time of use and which quickly decomposes when discarded. According to the present invention, there is provided a resin composition comprising an agent generating an acid or a base upon response to light or heat together with a hydrolyzable and biodegradable resin. The decomposable resin composition can promote decomposition of the polymer by generating an acid or a base in the resin by carrying out light irradiation and/or a heat treatment at a desired time and can control the decomposition speed of the polymer by controlling the generation amount of an acid or a base.

The resin composition according to claim 1, wherein an amount of the agent generating an acid by heating or the agent generating a base by heating is 0.1 to 20% by weight based on the hydrolyzable and biodegradable resin. 4. A method of treating a resin composition comprising the steps of: providing the resin composition comprising an agent generating an acid by heat and/or an agent generating a base by heat in a hydrolyzable and biodegradable resin; and subjecting the resin composition to heat treatment, wherein the hydrolyzable and biodegradable resin has the following structure: wherein (Sacch) denotes a saccharide structure and R denotes a group formed by removing two carboxylic groups from aliphatic or aromatic dicarboxylic acid. 5. A method of treating a resin composition comprising the steps of: providing the resin composition comprising an agent generating an acid by light and/or an agent generating a base by light together with an agent generating an acid by heat and/or an agent generating a base by heat in a hydrolyzable and biodegradable resin; and subjecting the resin composition to light irradiation and heat treatment, wherein the hydrolyzable and biodegradable resin has the following structure: wherein (Sacch) denotes a saccharide structure and R denotes a group formed by removing two carboxylic groups from aliphatic or aromatic dicarboxylic acid.
