The method of producing a polyvinyl butyral resin of the present disclosure enable manufacture of a film of which yellow index is low and durability is enhanced, when a film for lamination is manufactured, by advancing acetalization reaction of a polyvinyl alcohol resin and a butanal in the presence of a hydroxy butyric acid.

Method for preparing polyvinyl butyral resin composition, and glass-adhesive film comprising same

The present disclosure relates to a polyester resin composition including a polyester resin including a diol residue and a dicarboxylic acid residue, wherein the diol residue includes a cyclohexanedimethanol residue and the dicarboxylic acid residue includes an isophthalic acid residue and a terephthalic acid residue, wherein an amount of the isophthalic acid residue is 0 to 20 mol % when a total amount of the dicarboxylic acid residue is considered as 100 mol %, wherein an amount of the cyclohexanedimethanol residue is 50 to 100 mol % when a total amount of the diol residue is considered as 100 mol %, wherein the polyester resin composition includes an antioxidant, and wherein the antioxidant includes a phenol-based antioxidant, a phosphorus-based antioxidant, and a sulfur-based antioxidant.

Polyester resin composition, polyester film, and laminate for electronic device

A resin film for laminated glass, laminated glass including the resin film, and a process for manufacturing the laminated glass are disclosed. The resin film for laminated glass comprises a resin layer comprising a polyvinyl acetal resin and a contact surface in direct contact with glass, wherein the contact surface has an Rz roughness of 25 to 90 &#x3bc;m and a maximum static friction coefficient at 20&#xb0; C. of 0.85 to 1.60, and the compressive elastic deformation index measured in the perpendicular direction from the contact surface at 35&#xb0; C. is 40 to 310 &#x3bc;m/N.
