Abstract
Official abstract text for this publication.
Described is a resinous structure derived from fluorine-containing polymers useful as a mold having excellent dimensional stability.
First claim
Opening claim text (preview).
What is claimed is: 1. A resin mold comprising: a first surface where a plurality of first portions and a plurality of second portions are formed; and a second surface, wherein the resin mold is constituted of a first resin having a plurality of carbon-fluorine bonds, wherein the first resin is formed of a composition including a polymerizable constituent A1 having a unit represented by the following formula (a1) and a polymerizable constituent A2 having a unit represented by the 2. The resin mold of claim 1 , wherein a concentration of fluorine atom included in the first resin is greater than or equal to 20 wt %. 3. The resin mold of claim 1 , wherein a concentration of fluorine atom in the first resin is less than or equal to 76 wt %. 4. The resin mold of claim 3 , wherein the concentration of fluorine atom is greater than or equal to 24.8 wt %. 5. The resin mold of claim 1 , wherein a concentration of fluorine atom in the first resin is less than or equal to 32.1 wt %. 6. A method of using the resin mold of claim 1 to manufacture a plurality of components having a concavo-convex pattern, the method comprising: providing the resin mold with a concavo-convex surface; and repeating transfer printings from the resin mold to manufacture the plurality of components having a concavo-convex pattern.
