Wherein, the thickness of described sensitization discoloration layer is the 15-50 micron; and described sensitization discoloration layer is by the polyacrylate of 50-75wt%; 1 of 0.3-0.6wt%; benzoyl bromide between 3-diphenyl-4--5-pyrazolone; the aphthopyrans of 0.3-0.6wt%, the benzofuran-2-ones of 0.5-1.5wt%, the 2-hydroxyl of 0.25-0.50wt%-4-methoxyl-4 '-absolute ethyl alcohol of chloro benzophenone and surplus forms by gunite.
Wherein, the thickness of described uv absorption layer is the 10-20 micron; and described UV-absorbing layer is by the methacrylic acid octadecane alcohol ester of 50-75wt%; the benzofuran-2-ones of 0.5-1.5wt%, the absolute ethyl alcohol of acrylic acid-2-of 12.5-18wt% (4-benzoyl-3-hydroxyl-phenoxy group) ethyl ester and surplus forms by gunite.
Wherein, described eyeglass also comprises transparent antireflection layer, and the thickness of described transparent antireflection layer is the 5-25 millimeter, and it is by the aluminium oxide of 20-25wt%, the titania of 25-30wt%, and the titanium nitride of 20-25wt% and the aluminium nitride of surplus form.
Sensitization discoloration eyeglass of the present invention is compared with sunglasses of the prior art and sensitization discoloration eyeglass, has following beneficial effect:
(1) described sensitization discoloration eyeglass not only can be realized sensitization discoloration, and by design light absorption marker, can prevent unexpected a small amount of ultraviolet ray under indoor other condition such as grade and causes the sensitization discoloration layer that undesirable color change occurs; And described light absorption marker can absorption portion ultraviolet ray and then can further improve stability and the antioxygenic property of described sensitization discoloration layer.
(2) described sensitization discoloration layer adopts 1; the sensitization discoloration compound that benzoyl bromide between 3-diphenyl-4--5-pyrazolone and aphthopyrans are composite; compare with spiro-pyrans, Luo oxazine, nitrone class commonly used in the prior art; not only significantly reduced the consumption of sensitization discoloration compound; and the stability of described sensitization discoloration layer and fatigue resistence are good; sensitivity to light is also ideal, only needs 1-3 just can reach required color changeable effect second under sunny solar irradiation.
Description of drawings
Fig. 1 is the cut-open view of the described sensitization discoloration lens structure of embodiment.
Embodiment
Below with reference to embodiment and accompanying drawing technical scheme of the present invention is further described.
As shown in Figure 1, wherein, described eyeglass sets gradually UV-absorbing layer 31, sensitization discoloration layer 32, light absorption marker 33 and transparent antireflection layer 34 at transparent substrate (place not shown in the figures).The thickness of described uv absorption layer is the 10-20 micron; and the methacrylic acid octadecane alcohol ester by 50-75wt%; the benzofuran-2-ones of 0.5-1.5wt%, the absolute ethyl alcohol of acrylic acid-2-of 12.5-18wt% (4-benzoyl-3-hydroxyl-phenoxy group) ethyl ester and surplus forms by gunite.The thickness of described sensitization discoloration layer is the 15-50 micron; and the polyacrylate by 50-75wt%; 1 of 0.3-0.6wt%; benzoyl bromide between 3-diphenyl-4--5-pyrazolone; the aphthopyrans of 0.3-0.6wt%; the benzofuran-2-ones of 0.5-1.5wt%, the 2-hydroxyl of 0.25-0.50wt%-4-methoxyl-4 '-absolute ethyl alcohol of chloro benzophenone and surplus forms by gunite.The thickness of wherein said light absorption marker is the 2-5 micron, and the polyvinyl alcohol (PVA) by 50-75wt%, the triaryl of 0.1-0.25wt%-s-triazine, the benzofuran-2-ones of 0.3-0.75wt%, the vinyl trichlorosilane of 5-10wt% and the absolute ethyl alcohol of surplus form by gunite.Described eyeglass also comprises transparent antireflection layer, and the thickness of described transparent antireflection layer is the 5-25 millimeter, and it is by the aluminium oxide of 20-25wt%, the titania of 25-30wt%, and the titanium nitride of 20-25wt% and the aluminium nitride of surplus form.This antireflection layer can form by modes such as magnetron sputtering, evaporations.
