I kept warm. Then, 2.5 g of AIBN was added thereto and kept warm for 2 hours. The temperature was then adjusted to about 105 ° C.
- epoxy equivalent was 6,600 g / eq
- acryloyl equivalent was 349 g / eq
- weight average molecular weight in terms of standard polystyrene measured by GPC was 60,000.
- PCDL polycarbonate diol
- a melamine-based mold release agent was coated on one surface of a 50 ⁇ m thick PET film by a gravure coating method to form a release layer.
- the hard coating composition prepared on the release layer was applied to a thickness of about 6 ⁇ m by a microgravure coating method.
- the applied coating liquid was heated at 150 ° C. for 30 seconds to form a coating layer containing the thermosetting of the composition for hard coating, thereby preparing a sheet for hard coating formation.
- a hard coat-forming sheet was prepared in the same manner as in Example 1.
- Example 1 After coating the printing layer and the adhesive layer for imparting a decoration effect on the sheet for forming a hard coating prepared in Example 1 and Comparative Examples 1 and 2, sufficient Aging was performed. Thereafter, the resultant was stored in a low temperature chamber at a temperature of ⁇ 10 ° C. for 1 hour, then taken out and immediately injected, and then passed through a UV curing machine to evaluate moldability.
- Example 1 After coating the printing layer and the adhesive layer for imparting a decoration effect on the sheet for forming a hard coating prepared in Example 1 and Comparative Examples 1 and 2, sufficient Aging was performed. Then, after injection, slip properties were evaluated after passing through a UV curing machine.
- Table 1 shows the results of evaluation of physical properties of the sheet for forming a hard coating prepared according to Example 1 and Comparative Examples 1 and 2.
