Background technology
The most a large amount of templates, are widely used in packages printing field.Template is by trickle
Plant fiber by being interleaved with each other, under dampness through free beating, not applying glue, the most filled,
Copy paper, the concentrated sulphuric acid of 72% soaks 2～3s, with glycerin treatment after clear water washing, the one of dried formation
Plant the material of the hard film type of quality.Template quality is solid, dense and the most transparent, has oil
The permeation resistant of fat and water is strong, airtight, and the feature such as wet strength is big, can be waterproof, moistureproof, anti-
Oil, sterilize, sterilize.But solid just because of its surface compact, quality, cause template to turn in heat
During print, PUR is to its poor permeability.Although additionally, the surface tool after persulfuric acid, glycerin treatment
There is higher surface roughness, but different with other rag papers (body paper or tracing paper) surface, sulphuric acid
Paper surface does not possess substantial amounts of capillary fiber, and therefore, even if under hot pressing condition, ordinary hot melten gel is also
It is difficult to its surface is permeated.Adding, template permeability is poor, bubble during thermal transfer
Discharge the factor being also to need to consider.
At present, on market for the hot melt glue of thermal transfer be concentrated mainly on cork paper, UV ink paper,
UV light oilpaper, mistake mould the base material such as paper, PP or PE plastic material.The upper of template is scalded by these glue
Property poor, i.e. enable that part is upper scalds, pattern adhesive force is the most poor.Further, for the bonding of template or
Correlation technique or the invention of thermal transfer class did not the most have been reported that.
