Abstract
An interlayer film for a laminated glass and a laminated glass, which do not cause an increase in a haze value due to moisture absorption and have excellent moisture resistance are provided. An interlayer film for a laminated glass which contains a polyvinyl acetal resin and a moisture resistance improver is provided.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . An interlayer film for a laminated glass, which contains a polyvinyl acetal resin and a moisture resistance improver, wherein the content of the moisture resistance improver is 0.005 to 20 parts by weight with respect to 100 parts by weight of the polyvinyl acetal resin.
2 . The interlayer film for a laminated glass according to claim 1 , wherein the content of the moisture resistance improver is 0.01 to 5 parts by weight with respect to 100 parts by weight of the polyvinyl acetal resin.
3 . The interlayer film for a laminated glass according to claim 1 , wherein the moisture resistance improver is an amphiphile or a surfactant or both.
4 . The interlayer film for a laminated glass according to claim 1 , wherein the moisture resistance improver has a solubility parameter that is larger than the polyvinyl acetal resin and smaller than water.
5 . The interlayer film for a laminated glass according to claim 1 , wherein the moisture resistance improver has a solubility parameter in the range of 10.0 to 20.0 (cal/cm 3 ) 1/2 .
6 . The interlayer film for a laminated glass according to claim 1 , wherein the moisture resistance improver has a relative permittivity in the range of 20 to 35 at 25° C.
7 . The interlayer film for a laminated glass according to claim 1 , wherein the moisture resistance improver is a phosphate ester compound.
8 . The interlayer film for a laminated glass according to claim 1 , which contains a heat ray shielding particle.
9 . The interlayer film for a laminated glass according to claim 2 , wherein the moisture resistance improver is an amphiphile or a surfactant or both.
10 . The interlayer film for a laminated glass according to claim 2 , wherein the moisture resistance improver has a solubility parameter that is larger than the polyvinyl acetal resin and smaller than water.
11 . The interlayer film for a laminated glass according to claim 2 , wherein the moisture resistance improver has a solubility parameter in the range of 10.0 to 20.0 (cal/cm 3 ) 1/2 .
12 . The interlayer film for a laminated glass according to claim 2 , wherein the moisture resistance improver has a relative permittivity in the range of 20 to 35 at 25° C.
13 . The interlayer film for a laminated glass according to claim 2 , wherein the moisture resistance improver is a phosphate ester compound.
14 . The interlayer film for a laminated glass according to claim 2 , which contains a heat ray shielding particle.
15 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 1 .
16 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 2 .Join the waitlist — get patent alerts
