- non-polymerizable phosphoric ester conjugates those having a polymerizable functional group
- (meth) acrylic monomers Had low solubility in (meth) acrylic monomers. For this reason, the types of (meth) acrylic monomers that can dissolve the powerful non-polymerizable phosphoric acid ester conjugate have been limited.
- polymerizable phosphoric ester conjugates those having a polymerizable functional group (such compounds are hereinafter referred to as “polymerizable phosphoric ester conjugates”) are: ⁇ ⁇ ⁇ Excellent solubility in fat components. Therefore, according to this, it was found that a polymer layer having excellent translucency can be formed.
- the polymerizable composition containing such a polymerizable phosphoric acid ester conjugate had a tendency that the polymer was hard and brittle. For this reason, a laminated glass using such a polymerizable composition for the polymer layer was excellent in translucency, but poor in penetration resistance.

- Example 5 Thereafter, the temperature in the oven is raised to 110 ° C over 3 hours, and then maintained at the same temperature for 3 hours to perform polymerization and curing of the polymerizable composition, thereby forming a polymer of the polymerizable composition. A polymer layer was formed. After cooling, the polyester tape wrapped around the side was peeled off to obtain a laminated glass of Example 5.
- a laminated glass was manufactured in the same manner as in Example 5, except that the polymerizable composition of Example 1 was replaced with the polymerizable composition of Examples 2 to 4 and Comparative Example 1 to L1.
- the use of the polymerizable compositions of Examples 2 to 4 corresponds to Examples 6 to 8
- the use of the polymerizable composition of Comparative Example 1 to L1 corresponds to Comparative Examples 12 to 22, respectively.
- the polymerizable compositions of Comparative Examples 6 to 11 could not carry out the polymerization reaction because the phosphoric acid ester-containing compound containing copper was not sufficiently dissolved in the monomer, and the resulting laminated glass was , Can not be subjected to the following characteristic evaluation.
- the laminated glasses of Examples 5 to 8 and Comparative Examples 12 to 16 were sandwiched between two stainless steel frames each having an outer frame size of 230 mm ⁇ 230 mm and an inner frame size of 150 mm ⁇ 150 mm, and fixed horizontally.
- a chrome steel ball with a diameter of 63.5 mm and a mass of 1044 g is dropped freely from the height of 80 cm to the vicinity of the center of the laminated glass on each of the laminated glasses fixed in this way, and between the glasses when the glass breaks.
- the degree of breakage of the disposed polymer layer was visually confirmed. Table 2 shows the obtained results.
- the first phosphoric acid ester conjugate having a polymerizable functional group and no aromatic ring, and both the monoester and the diester having no polymerizable functional group were used.
- the laminated glass (laminate; Examples 5 to 8) in which the polymer layer was formed from the polymerizable composition containing the second phosphoric acid ester compound, which has a low haze, has a high translucency. It was proved that the chromium steel ball had excellent penetration resistance since it did not break, and that it had excellent penetration resistance.
