Title: Selectively dyed polyester resin composition, method for manufacturing it and forming product thereof
Inventor: JEONG HYAN WOO
IPC: C08L67/06
Filed: 1998-11-07
Abstract: PURPOSE: A selectively dyed unsaturated polyester resin composition is provided, which is used for producing partially dyed button. CONSTITUTION: The composition is the same as the existing ortho based resin composition except including iso-phthalic acid instead of ortho-phthalic acid. O-phthalic acid has the advantage of good transparency and low cost and widely used, but has the limit to the selective or partial dyeing because of total dyeing in the after-dyeing process. Dyeing is impossible in the after-dyeing process using iso-phthalic acid instead of O-phthalic acid, so partial and selective dyeing is only possible mixing it appropriately.
