Description
Technical field
The present invention relates to cosmetic sheet.
Background technology
All the time, the known cosmetic sheet that pattern layer, transparent resin bed and transparent surface protection layer laminate are arranged at the substrate sheets superimposed layer.For example; in patent documentation 1; disclose on the substrate sheets that constitutes by polyolefin resin, be formed with pattern layer, transparent adhesive phase, transparent polypropylene-based resin layer successively and the cosmetic sheet of the transparent sealer that constitutes by ionizing radiation curing type resin.The substrate sheets of this cosmetic sheet and transparent resin bed form by synthetic resin, promptly are called so-called double-deck mode (with reference to Fig. 2).In double-deck mode,, then carry out bending machining easily if the aggregate thickness of substrate sheets and transparent resin bed is more than the 100 μ m.
But, the cosmetic sheet of above-mentioned double-deck mode, after carrying out bending machining, the problem that exists transparent resin bed generation albefaction, design property to reduce easily.And owing to have transparent resin bed on the pattern layer, so exist under the situation of fuzzy (dirt etc.) on the transparent resin bed, the distinctiveness of pattern reduces easily.In addition, owing to have the pattern layer in the middle of substrate sheets and the transparent resin bed, so the bonding force between substrate sheets and the transparent resin bed descends easily in time.And, owing to need implement weather-proof processing to transparent resin bed, so production cost improves easily.
To this, proposed not to be provided with transparent resin bed and be the above cosmetic sheet (so-called individual layer mode) (with reference to Fig. 3) of 100 μ m the thickness setting of substrate sheets (synthetic resin layer).In this individual layer mode, because the thickness of synthetic resin layer is bigger, so carry out bending machining easily.And, since with substrate sheets as dyed layer, the problem of albefaction in the time of can not producing bending.But, in order to prepare the big substrate sheets of thickness, the problem that production cost improves has easily appearred.
As the improvement of double-deck mode, also proposed not to be provided with substrate sheets and be cosmetic sheet (so-called back up (back print) mode) (with reference to Fig. 4) more than the 100 μ m the thickness setting of transparent resin bed.In this back up mode, though do not need to prepare substrate sheets, but owing to need to prepare the big transparent resin bed of thickness, and need implement weather-proof processing to transparent resin bed, so production cost improves easily, also there is the easy problem that reduces of distinctiveness of pattern when existence is fuzzy on the transparent resin bed.
Therefore, press for the cosmetic sheet that exploitation can improve these existing product defectives.

Comparative example 1
Form by going up printed patterns flower-pattern layer (2 μ m) at the thick coloured polypropylene sheet (substrate sheets) of 60 μ m.Then, use polyurethanes dry lamination adhesive, the transparent polypropylene resin film that 0.08mm is thick (transparent resin bed) is bonded on the pattern layer.Wherein, the thickness of transparent adhesive phase is 3 μ m.Then, coating biliquid curable polyurethane resinoid forms priming coat (thickness is 2 μ m) on transparent resin bed.On priming coat, form electron ray curing type transparency sealer (5 μ m) then.Implement embossing processing from transparent sealer one side then, make cosmetic sheet.In embossing processing, give the wood grain conduit decorative pattern about the degree of depth 30 μ m.
Comparative example 2
By printing, on the thick transparent polypropylene foil of 120 μ m, form pattern layer (2 μ m) according to the order of pattern, full coat.Coating biliquid curable polyurethane resinoid on the opposing face of the sheet that is provided with pattern forms priming coat (thickness is 2 μ m) then.Then on priming coat, form electron ray curing type transparency sealer (5 μ m).Implement embossing processing from transparent sealer one side then, make cosmetic sheet.In embossing processing, give the wood grain conduit decorative pattern about the degree of depth 30 μ m.

| Crooked albefaction | ○ | ○ | △ | △～× |
| Design property | ○ | ○ | △ | △ |
Test method
" crooked albefaction "
With sample (5 ℃) bending at low temperatures, and change by the visualization evaluation.
Zero confirms less than albefaction
△ confirms a little albefaction
* obviously affirmation has albefaction, crackle
" evaluation of design property "
Distinctiveness by monitoring experiment (visualization) evaluation pattern generating decorative pattern.
The distinctiveness of the above evaluation design of 0 10 philtrums, 6 people is good
It is good that △ 10 philtrums 4 or 5 people estimate the distinctiveness of design
It is good that * 10 philtrums have only 0～3 people to estimate the distinctiveness of design
