JP-A-8-57866 discloses a resin composition for mold cleaning which can be filled with a complicated mold or a large mold for mold cleaning, which comprises an amine-based resin composition and a lubricant having an HLB value of 1.5 to 8. With the increasing compactness, reduced thickness, and surface lamination of IOLSI, the configuration and structure of molded objects have been diversified to be extremely small devices with a gate size of X·4 X 0.4 mm (mm) and 1.2 to An extremely thin device with a gate size of 1.5 mm and a thickness of about 0.03 to 0.04 mm is added. The resin composition for mold cleaning applied to such an ultra-thin mold or matrix mold as described above is currently insufficient. In recent years, there have been various thermosetting resin molding materials for sealing IOLSI which can be obtained because the composition of the molding material to be used must be changed depending on the desired characteristics. Therefore, the conditions for the mold to be stained by the reverse mold and the composition of the stain are various. In particular, the molding material mainly comprises a biphenyl type epoxy resin, a polyfunctional epoxy resin or a dicyclopentadiene type epoxy resin which has replaced the conventional phenolic epoxy resin, when repeatedly molded due to the glue Living caused a considerable amount of mold contamination. A biphenyl type epoxy resin and a polyfunctional epoxy resin cause particularly significant staining and the number of moldings required for the mold cleaning resin composition suggested above to be significantly increased for the complete removal of the mold Dirt, which causes a problem of greatly reduced productivity of IOLSI. In order to completely fill an ultrathin or matrix mold with a mold cleaning resin composition, the mold cleaning resin composition must have improved fluidity without impairing cleaning performance and dissociable property.

The old finger dirt and the mold adhesion is stronger than the mold cleaning resin composition and The adhesion between dirt. In other words, the deterioration in cleaning performance is caused by an increase in the adhesion between the mold and the dirt or a decrease in the adhesion between the mold resin for cleaning the mold and the dirt. Reducing at least one of these factors, and preferably both, will result in improved cleaning performance. Means for removing the factor causing the deterioration of the cleaning performance include improving the strength of a molded article of a mold for cleaning a mold, improving the modulus of a molded article of a mold for cleaning a mold, and improving the cleaning of a mold. The bonding between the molded article of the resin and the dirt. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. SUMMARY OF THE INVENTION An object of the present invention is to provide a mold cleaning resin composition which has improved workability in cleaning even a very small or extremely thin mold and can remove various stains. The inventors of the present invention previously proposed in WO 02/30648 A1 a resin composition for mold cleaning for removing contaminants accumulated on the surface of a mold which is overmolded. A molding material mainly comprises a type of joint. A benzene type epoxy resin, a polyfunctional epoxy resin or a dicyclopentadiene type resin is a result of those commonly used as an epoxy resin.
