。Conventionally, in order to prevent reflection of synthetic resin lenses such as acrylic resin, a heat-cured film of organopolysiloxane resin is formed as the first layer, and a 5ins film, S
The fact that it is sufficient to form a tO film or the like as an antireflection layer is a general rule detailed in JP-A-54-23557. Furthermore, in the case of lenses having a relatively large radius of curvature, such as eyeglass lenses, when the organopolysiloxane resin layer is provided, dip coating υ, which is pulled up at a uniform speed, has been used for coating. This is because, for eyeglass lenses, only the central portion of the lens is used to fit into the eyeglass frame, and surface precision is not required to be very high. The film thickness by dip coating is determined by the viscosity of the coating solution, the speed at which the lens is pulled up, and the angle between the coating surface and the solution, so it is applied to lenses with relatively small curvature used in cameras, etc., and to eyeglass lenses. The reason for applying the organopolysiloxane resin layer using a dip coating method with a constant pulling rate as described above is that during dipping and coating, the angles formed with the solution at each point on the lens are significantly different, so the film thickness may vary. trembles greatly,
It was very difficult to obtain a layer with good uniformity.

1), as the organopolysiloxane resin coating bath Group 1, Nic Coat (manufactured by Katsuta Kako: trade name) diluted by a factor of 25 with isopropyl alcohol was used, and an angle θ was given to the acrylic plate 2. Apply the solution. At this time, the angle of the top surface was set as ((-)), and the angle of the bottom surface was set as (-). It was found that the coating thickness changes depending on the angle and lifting speed.Therefore, when coating a lens as shown in Figure 5, the angle θ between the lens surface and the liquid level changes every moment as the liquid is pulled up, so the coating film can be coated at a uniform speed. It is not possible to apply the film to a uniform thickness by pulling it up.For example, when coating a biconvex lens with a maximum angle of 45', the film thickness distribution is 4 times different between the upper and lower ends of the lens and the center when it is pulled up. When the minimum coating thickness is 1 μm, the film thickness varies from 1 to 4 μ7 nm, and the surface precision deteriorates significantly.Therefore, based on the above experimental results, the present invention has developed a lens that maintains a constant film thickness. It is characterized by changing the pulling speed according to the contact angle between the surface and the surface of the coating solution.For example, when a lens with a film thickness of When applying organopolysiloxane resin to 2μnL, first plot the speed according to the angle from Figure 2 as shown in Figure 5.Next, for the claw piece 1tχ from the top end of the lens when pulling up Plot the contact angle θ between the lens field surface and the solution surface as shown in Figure 6. Next, change the vertical and horizontal axes of Figure 5 and plot as shown in Figure 7. Regarding Fig. 8, which has the same horizontal axis and the vertical axis is the pulling time, from the value of The above process is plotted in Figure 8. The above process is a rough outline for obtaining the relationship between the pulling speed and the pulling time, but in actual use it can be performed by combinator control. In order to strictly apply the method of the invention, it is limited to lenses that are biconvex or biconcave and have the same curvature, but in reality it is 0.5μ7n.
Since a film thickness variation of up to 8 degrees is allowed, the pulling speed can be varied depending on the combination of the curvatures of each lens, making it possible to keep the surface precision within the allowable range.
