The invention relates to high-gloss thermosensitive paper and a manufacturing process thereof, wherein a base paper layer, a prime coat layer, a thermosensitive
chromogenic layer and a top
coating protection layer are sequentially arranged from bottom to top. The manufacturing process comprises: (1) selecting a
coating substrate; (2) preparing a prime coat later
coating liquid; (3) preparing a thermosensitive
chromogenic layer coating liquid; (4) preparing a top coating
protection layer coating liquid; and (5) respectively beating each coating liquid into the material grooves of a coating
machine, sequentially coating a paper base material with a prime coat layer, a thermosensitive
chromogenic layer and a top coating
protection layer by using a metering rod coating method, discharging outof the
machine, carrying out
calendering, and sub-
cutting to obtain the finished product, wherein the three
layers are coated at one time. According to the present invention, the coating surface of the product has significant gloss, the gloss can reach 60-70% according to the different abilities of the
calendering equipment during the
processing, and after the product is printed, the thermosensitive color developing part is black and has
bright light effect so as to achieve the beautiful thermosensitive printing effect.
