- an interlayer film for laminated glass and a laminated glass were produced.
- Example 2 except that the amount of alkali metal was 41 ppm by adding potassium octoate and magnesium was added by adding magnesium octoate to 15 ppm instead of adding magnesium hexanoate. In the same manner, an interlayer film for laminated glass and a laminated glass were produced.
- magnesium hexanoate By adding magnesium hexanoate, the amount of magnesium was 20 ppm, and instead of adding potassium otanate, potassium hexanoate was added, so that the amount of alkali metal was 53 ppm.
- an interlayer film for laminated glass and a laminated glass were produced.
- magnesium acetate is added to bring the amount of magnesium to 60 ppm, the added amount of acetylacetylacetone to 0.01 parts by weight, and the power to add potassium octanoate.
- An interlayer film for laminated glass and a laminated glass were produced in the same manner as Example 2 except for the above.
- An interlayer film for laminated glass and a laminated glass were produced in the same manner as in Comparative Example 6 except that magnesium hexanoate was added instead of adding magnesium acetate so that the amount of magnesium was 60 ppm.
- an interlayer film for laminated glass and a laminated glass were produced in the same manner as in Comparative Example 8, except that 0.05 part by weight of silicone oil was added.
- the obtained laminated glass was placed under conditions of 50 ° C. and humidity of 97% for 24 hours, and the following evaluation was performed visually.
- the resulting laminated glass was adjusted to a temperature of 18 ° C ⁇ 0.6 ° C for 16 hours, and the center of this laminated glass (length 150mm x width 150mm) was struck with a hammer with a head of 0.45kg. Then, the glass was pulverized until the particle size of the glass became 6 mm or less, and the degree of exposure of the film after the partial peeling of the glass was measured.
- the obtained laminated glass was allowed to stand at 50 ° C., and the pummel values were measured after 2 weeks and 4 weeks.
- the changes in the pummel values between the initial pummel value, 2 weeks and 4 weeks were as follows. Evaluation was based on the following criteria.
- the present invention it is possible to prevent the occurrence of colored spots on the metal coating on the glass surface due to the residual alkali metal, excellent penetration resistance, change with time in the adhesive force with glass, and build-up ( It is possible to provide a laminated glass interlayer film and a laminated glass with almost no generation of color streaks in the interlayer film for laminated glass.
