  • Patent number: 11561468
    Abstract: A pattern forming method comprises dispensing a curable composition onto an underlayer of a substrate; bringing the curable composition into contact with a mold; irradiating the curable composition with light to form a cured film; and separating the cured film from the mold. The proportion of the number of carbon atoms relative to the total number of atoms in the underlayer is 80% or more. The dispensing step comprises a first dispensing step of dispensing a curable composition (A1) substantially free of a fluorosurfactant onto the underlayer, and a second dispensing step of dripping a droplet of a curable composition (A2) having a fluorosurfactant concentration in components excluding a solvent of 1.1% by mass or less onto the curable composition (A1) discretely.

  • Patent number: 11529779
    Abstract: A lens with an embedded foil is produced by positioning a foil on a holder, providing adhesive attachment dots on the foil on surface portions opposite to the holder, positioning a front mould ensuring the contact of the dots with a front mould surface, retracting the holder and positioning a back mould opposite to the front mould. The mould is then connected with a sealing bridge to build an assembly forming a mould cavity with a pouring opening. The edge of the foil is spaced apart from the bridge and the assembly has passages between the dots, the foil, and the front mould surface allowing pouring a monomer into the cavity before curing the monomer, decomposing the assembly and cutting the lens from the polymer block.
