摘要:
Provided herein is an improved spin coating system and a method of using the spin coating machine to produce an optical article. The system includes at least one dispensing arm assembly. The holder assembly is moveable along a substantially vertical axis. The dispensing arm assembly has a base and at least one arm having a first end and a second end and is moveable along a horizontal axis. The at least one arm is operably coupled to the base at the first end and operably coupled to at least one applicator at the second end, and the applicator is capable of being positioned along the substantially vertical axis. The method includes depositing a primer layer onto a lens using the dispensing arm assembly, followed by a hard coating, and drying and cooling the substrate using a drying/cooling station that is positioned substantially along the substantially vertical axis.

An optical substrate 1 according to one embodiment comprises a support substrate 2, and a projection-depression structure layer 3 on a surface of which shapes of projections and depressions are formed, the projection-depression structure layer 3 being laminated on the support substrate 2. The extending directions of projection portions contained in the projection-depression structure layer 3 are irregularly distributed seen in planar view. An outline X seen in planar view of a projection portion contained in a region per unit area of the projection-depression structure layer 3 includes more straight line sections than curved line sections.

A spin coater that can be used to apply multiple coating compositions over an optical substrate, is described. The spin coater includes, a coater bowl configured to collect excess coating material expelled from an optical substrate being coated, a rotatable chuck configured to receive and rotate the optical substrate in the bowl during coating, a plurality of coating reservoirs, each containing a coating material, and an indexable coating reservoir platform containing the plurality of reservoirs and configured to index a selected reservoir into a dispensing position above the coater bowl. The spin coater can include or have associated therewith at least one curing station, in which each curing station is independently configured to cure at least partially at least one applied coating material. Each curing station can include at least one of a thermal curing station, a UV curing station, and/or an IR curing station.

A functional laminated spectacle lens is provided which includes, as constituent layers, an outer lens (1), a polarizing film (2), and an inner lens (3) which are layer parts, and which is obtained by: forming a functional layer(s) (D 1 , D 2 , D 3 and/or D 4 ,) on at least one of the constituent layers; forming adhesive layers (4 and 5) on the functional layer(s); and laminating and integrating other constituent layers, with the adhesive layers (4 and 5) being interposed therebetween. In the functional laminated spectacle lens, each of the functional layers (D 1 , D 2 , D 3 and D 4 ,) is formed using a spin coating material, which is characterized by being obtained by incorporating a functional pigment into an acrylic urethane resin which comprises, as a main component, an acrylic polyol containing 4-hydroxybutyl acrylate, and, as a curable component, a polyisocyanate. In the functional layer obtained by curing the spin coating material, the required functional pigment is reliably maintained in the functional layer by a three-dimensional network structure, the migration of the functional pigment into an adjacent resin monomer-containing layer is prevented, and the functional pigment is made less susceptible to the effect of an organic peroxide contained in the resin.

A coating solution (3) is injected from nozzles (2a, 2b) in the horizontal direction to coat, with the coating solution (3), lens surfaces (1a, 1b) of a spectacle lens substrate (1) so arranged as to orient an optical axis (C) in the horizontal direction (step S2a). The spectacle lens substrate (1) is rotated at a first rotational speed about the optical axis (C) serving as the rotation center, and the coating solution (3) is spread on the lens surfaces by the centrifugal force (step S2b). The spectacle lens substrate (1) is rotated at a second rotational speed higher than the first rotational speed to blow away an excess (3a) of the coating solution (3) from the spectacle lens substrate (1) by the centrifugal force (step S3). Highly uniform films can be formed on the lens surfaces of the spectacle lens.

The invention intends to provide a method for preventing deterioration in quality of the primer layer resulting from spinning-off and reattachment of a primer liquid on forming a polyurethane primer layer on a substrate for an eyeglass lens or the like using a coating composition containing a moisture-curing polyurethane resin. The method for producing a laminate according to the present invention comprises performing spin-coating while a spin-coating apparatus is forcefully evacuated through the side wall and/or the bottom thereof, on producing a laminate by spin-coating the surface of a substrate with a coating composition containing a moisture-curing polyurethane resin. More preferably, the spin-coating apparatus comprises a top cover, a lower chamber, and a rotatable substrate supporting device installed in the lower chamber; exhaust ports are provided in the top cover and at the bottom of the lower chamber; and the substrate supporting device is housed in a cylinder member wherein the aperture of at the lower end is larger than the aperture at the upper end.
