The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

Referring to fig. 1-4, the novel thermal paper comprises a paper body 1 and a roll core 2, wherein the paper body 1 is in a square strip shape, and the overall length is generally within 10m, and is most suitable for about 5 m. The paper body 1 comprises a base paper body layer and a base paper body layer, wherein a thermosensitive material is coated on the whole first surface 3 of the base paper body layer so as to form a thermosensitive color-changing layer. The common heat-sensitive material comprises two components, namely a leuco dye and a color-developing agent, wherein the common leuco dye comprises Crystal Violet Lactone (CVL) of a trityl phthalide system, leucobenzoyl methylene blue and the like, and the common color-developing agent comprises salicylic acid, 2, 4-dihydroxy benzoic acid and the like.

And a second surface 4, opposite to the first surface 3, of the base paper body layer is coated with an adhesive material to form an adhesive tape 5. The adhesive material adopts removable adhesive, the components of the adhesive are polyacrylate microemulsion, a user can repeatedly stick and take off the adhesive material, the user can adjust the sticking position for many times, and the use mode is more flexible.

The adhesive tape 5 is integrally formed along the extending direction of the base paper body layer, that is, the length of the adhesive tape 5 is equivalent to the base paper body layer, and the width thereof is narrower than the base paper body layer, and the position thereof is generally set to be deviated to one side in the width direction.

The paper body 1 is strip-shaped, the head and the tail are end edges, the other two edges are side edges, the paper body can be wound on the periphery of the winding core 2 in a stretching mode, in the winding state, the first surface 3 of the base paper body layer faces outwards, and the second surface 4 faces inwards.

When the thermal sensitive paper unfolding device is used, the rolled thermal sensitive paper is installed in corresponding equipment, the thermal sensitive paper is driven to rotate relative to the winding core 2 of the thermal sensitive paper after the equipment is started, so that the paper body 1 is unfolded and released according to a certain length, the content to be displayed is printed on the first surface 3 of the released paper body 1, and then a user can tear the paper body 1 with the length along the paper outlet of the equipment. The part of the thermal sensitive paper with the display content can be adhered to the corresponding desktop and wall surface through the adhesive tape 5, so that the user can watch the thermal sensitive paper conveniently at any time.

The adhesive tape 5 is provided along the entire extension direction of the base paper body layer, so that the adhesive tape 5 having a corresponding length can be used for adhesion regardless of the length position at which the thermal paper is torn. Meanwhile, the adhesive tape 5 is narrow in width, so that when a user holds the thermosensitive paper printed with contents, the user can avoid the adhesive tape 5, and the adhesive tape 5 is prevented from being in contact with fingers.

When printing, the heat-sensitive part of the thermal paper is inked under the action of the heat of the printing head, and the non-heat-sensitive part is not discolored, so that the contents such as characters, figures and the like are formed. Therefore, the thermosensitive color-changing layer can be coated with a protective material to form a protective layer, the protective material generally comprises a bridging agent, a lubricant and the like, and after contents are formed, the protective layer can slow down the deterioration of the thermosensitive paper and prolong the display life of the contents. Meanwhile, under the influence of the components of the thermosensitive color-changing layer and the protective layer, the first surface 3 of the paper body 1 is smooth, the viscosity between the adhesive tape 5 of the second surface 4 and the first surface 3 in the winding state is not too strong, and the unfolding of the thermosensitive paper is not influenced.

Specifically, referring to fig. 2, in one embodiment, the adhesive tape may be provided in a strip, and the strip of adhesive tape is biased toward one of two sides of the second surface of the base paper body layer. Referring to fig. 3, in another embodiment, two adhesive tapes are provided, and one adhesive tape is biased to one side of the second surface, that is, one side of each of the two adhesive tapes is close to each of the two sides of the second surface.

Referring to fig. 2 and 4, between the adhesive strip 5 and the margin thereof biased towards one side edge is a void strip 6 of uncoated adhesive material. The adhesive tape 5 is biased to one side, and when a certain distance is kept from the margin of the side edge, the effect of this arrangement is that it can reduce the adhesion of excessive dust on the edge of the rolled thermal paper in a storage environment.

Specifically, the state of the roll-shaped transparent adhesive can be referred to in ordinary life, when the roll-shaped transparent adhesive is stored and placed, a lot of dust is often adhered to the side edge of the roll-shaped transparent adhesive, because the whole inner surface of the transparent adhesive has viscosity, and the side surface of the roll-shaped transparent adhesive inevitably generates viscosity due to overflow of the adhesive, so the roll-shaped transparent adhesive is easy to be stained with dust. In the case, the gap belt 6 is left at the edge of the rolled thermal paper, so that the adhesive belt 5 is effectively prevented from generating viscosity at the side wall, and the neatness of the thermal paper is kept.

In order to be better suitable for the application environment, the width range of the thermal paper body 1 is as follows: 50-60mm, wherein the width range of the adhesive tape 5 is: 4-15mm, for example, a single adhesive strip may be provided, the width of which may take a larger value, for example 11mm, or two adhesive strips may be provided, the width of which may take a smaller value, for example 4 mm. The width of the gap belt 6 is 1-3 mm; preferably, the width of the paper body 1 is 56.2mm, the width of the adhesive tape 5 is 11mm, and the width of the gap tape 6 is 2 mm. The device can be matched with common printing equipment, and is convenient to post and display due to the moderate size.

A positioning sticker (not shown) can be configured for the rolled thermal paper, and is generally configured when the thermal paper leaves a factory, one end of the positioning sticker is attached to the tail end of the paper body 1, the other end of the positioning sticker is attached to the body of the rolled thermal paper, so that the unused thermal paper can be limited in a winding state through the positioning sticker, and the positioning sticker can be removed when the thermal paper is to be used.

In conclusion, the improved thermal paper is provided with the adhesive tape 5 reasonably, so that the attaching and fixing mode of the thermal paper and corresponding carriers such as a desktop and a wall surface is improved, the operation is simple and convenient, the realization is easy, and the damage to the corresponding carriers is avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, which may be modified, combined, and varied by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
