Definitions

  • a pressure-sensitive decalcomania is formed of a support sheet containing a plurality of indicia with an adhesive coating covering the indicia and the adjacent surface of the support sheet. Selected solvents are employed in the adhesive coating for transferring the indicia to a receiving surface while retaining the adhesive coating surrounding the transferred indicia on the support sheet.
  • the present invention relates to dry decalcomanias which do not require either water or heat for transfer to a. receiving surface and, more particularly, to pressuresensitive decalcomanias employing an adhesive coating containing two different solvents which assist in the transfer of indicia from a support sheet to the receiving surface.
  • the support sheet is transparent or translucent and may have a mat or shiny finish on one or both of its faces.
  • a plurality of linked indicia such as letters, numbers, symbols and the like, are deposited by a printing process, for example, offset, typography, seriography or heliogravure processes, and a pressure-sensitive adhesive coating is applied to the indicia and to the surface of the support sheet about the indicia.
  • the coating is applied to the entire surface of the support sheet. Accordingly, it is necessary that the adhesive coating adhering directly to the non-porous surface of the support sheet be retained on the sheet at the time anindicia or number of indicia is transferred to a receiving surface. It can be appreciated that the transfer of additional adhesive coating to the receiving surface can interfere with its appearance or can have a tendency to collect dust about the periphery of the indicia.”
  • a protective sheet When not being used for transferring indicia to a receiving surface, a protective sheet is applied to the surface of the support sheet containing the indicia to prevent any accidental transfer of the indicia.
  • a protective sheet having a surface treated with silicon is effective forthis purose. g p
  • Another important object of the invention is to provide an adhesive coating for the transfer of the indicia to a receiving surface which embodies certain materials capable of assisting in the transfer of the indicia while maintaining the remainder of the coating on the support sheet.
  • the invention provides improvements in the transfer of pressure-sensitive decalcomanias from a support sheet to a receiving surface by providing an adhesive coating over a non-porous surface of the support sheet containing the indicia with the adhesive employed assisting in the removal of the indicia from the support sheet due to a phenomenon of migration effected by solvents contained within the adhesive.
  • a sheet preferably formed of a transparent or translucent plastic material, is imprinted on a non-porous surface thereof with a plurality of indicia using a printing material such as ink or the like which has a low degree of adhesion or mechanical bond to the support sheet and has practically no chemical action with the support sheet.
  • the molecules of the printing ink have an electro-chemioal charge of a certain polarity. In a polar liquid the electrical center of gravity falls outside the mechanical center of gravity. The negative charge is farther away from the core.
  • electro-chemical charges in a material reference is made to fTheory of Electric Polarisation, 1952 C. J. F.
  • a pressure-sensitive adhesive substance is coated onto the sheet covering all of the indicia and the adjacent surfaces of the sheet.
  • the adhesive contains at least two solvents, one of which has an electro-chemical charge opposite in polarity to that of the electro-chemical charge of the printing material used in placing the indicia on the support sheet and, the other solvent is not provided with a charge which attracts it to the molecules in the printing ink.
  • the first solvent due to the opposite character of its charge relative to the charge on the printing material or ink forming the indicia, forms abond about the individual molecules of the printing substance and provides the body of material forming the indicia with a certain degree of porosity. Due to this porosity, the second solvent, since it is not attracted to the charges molecules of the printing material, infiltrates through the indicia and comes into contact with the surface of the support sheet under the indicia.
  • the presence of the second solvent at the interface between the indicia and the support-sheet effects a reduction in the adhesion of the indicia to the sheet, because it contains a charge of the same character as the charge of the ink, so that the indicia which is mechanically but not chemically bonded to the support sheet can be easily transferred to a receiving surface by the application of pressure on the opposite surface of the support sheet.
  • the materials used to form the coating are specifically selected to aid in the separation of the indicia from the support sheet and to afford a shearing of the adhesive coating at the lateral peripheral boundaries of the indicia.
  • the migrating solvents that is, the solvents passing through the indicia may contain other elements of materials for the following purposes.
  • the amount of the different solvents should be carefully proportioned whereby the bonding of the indicia to the support sheet is broken, but, the cohesiveness of the adhesive coating at the edges of the indicia is not sheared and, as a result, the indicia is retained on the support sheet.
  • the migrating solvents may also include certain deactivating elements. These deactivating elements can effect a change in the adhesive quality of the coating covering the indici-a and provide it with a greater adhesive ability.
  • a matting agent included 'in the adhesive material can provide a mat appearance to the surface of the indicia when the material infiltrates through the indicia to the surface of the support sheet.
  • the effect on the matting agent can be particularly noted since it infiltrates through the indicia and becomes apparent through the surface of the support sheet at the interface with the indicia.
  • the support sheet has a non-porous surface on which the indicia are deposited and is formed of a material, preferably transparent or translucent, for affording good registration in the transfer of the indicia to a receiving surface.
  • the surfaces of the support sheet can be dull on one or both sides or polished on one or both sides, while the thickness of the sheet can vary Within Wide limits ranging between 0.0010 to 0.010 inch.”
  • the indicia are formed of a substance having ,good physical drying properties which form, after the evaporation of the solvents, a flexible film-like member on the support sheet.
  • the indicia can be applied by any known method of printing or coating.
  • the printing materials employed in forming the indicia should form a weak or limited bond with the surface of the support sheet, therefore, it is not recommended that substances be employed in forming the indicia which would tend to adhere strongly to the support sheet.
  • a flexible film-like member is formed on the support surface which can be transferred as a unit to a receiving surface.
  • the substance used should be sensitive to the action of certain solvents contained in the adhesive material used as the coating since this characteristic is indispensible where the phenomenon of migration is employed.
  • the adhesive solution applied to the outer surfaces of the indicia on the support surface as well as to the remaining surface thereof is diluted with a combination of at least two solvents:
  • the first or type I solvent carries an electro-chemical charge opposite to that impressed on the indicia and forms a film which covers or encloses and is, due to the opposite nature of the electrostatic charge, bonded to the indicia.
  • the interaction of the first solvent and the indicia cause a swelling and the indicia develop a degree of p0- rosity which permits the infiltration of the second or type II solvents through the indicia.
  • As the type I solventa ketone and/or glycol can be used.
  • the second or type II solvent is not attracted to the substance forming the indicia and thus it is possible for it to infiltrate through the indicia to the interface shared with the support sheet.
  • the second solvent can include a small percentage of a solvent which is attracted to the surface of the support sheet by reason of the pressure of opposite electro-chemical charges in the solvent and in the support sheet to facilitate the migration of the solvent through the indicia.
  • the percentage of this additional solvent must be limited since too great an infiltration of the second solvent through the indicia would result in totally detaching it from the support sheet.
  • the type II solvents can serve as a vehicle or carrier for other elements mixed into the adhesive solution, and with which they are soluble.
  • As the type II solvent aliphatic and aromatic compounds can be used.
  • FIG. 4 is a partial sectional view illustrating the support surface containing several indicia encircled by the adhesive coating.
  • an indicia 2 is shown imprinted upon a nonporous support surface 1, and while only one indicia is shown, it will be appreciated that the support-surface can contain a great number of indicia in a relatively closely spaced arrangement.
  • the material forming the indicia is mechanically bonded to the non-porous support-surface, but it has practically no chemical action with the support sheet.
  • the adhesive solution 3 (FIG. 2) is deposited across the entire surface of the support sheet and a relatively thin layer 3' is superposed on the face of the indicia directed outwardly from the support sheet.
  • the support sheet 1 is shown overlying a receiving surface 10.
  • the support sheet or at least the adhesive coating 3, 3' is in contact with the receiving surface 10.
  • the adhesive coating 3 on the outer surface of the indicia is bonded to the receiving surface and the infiltration of the second solvent in the adhesive coating has provided a surface 4 of reduced attachment between the interface of the support sheet and the indicia so that after the pressure has been applied to the support sheet, the indicia adheres to the receiving surface and separates both from the surface 4 of the support sheet and from the adjoining coating 3 on the support sheet.
  • the ability of the indicia to separate from the enclosing portions of the adhesive coating disposed about its peripheral boundaries is explained due to the high degree of adhesion of the coating 3 to the surface of the support sheet while within the boundaries of the indicia, the solvents have combined to provide a separation of the indicia from the opposed surface of the support sheet.
  • the reduced thickness of the coating 3' over the indicia 2 and the infiltration of the solvents through the indicia provide the required effect for achieving a clean shear or rupture action between the different portions of the adhesive coating 3, 3'.
  • FIG. 4 the manner in which the different solvents within the adhesive coating 3 act is shown in a schematic arrangement in which the hatched parts 2a designate the molecules of the indicia and the open circles 5 define the molecules of the first or type I solvent which are attracted and bonded to the molecules of the indicia.
  • Disposed outwardl'y" of and between the molecules and the molecules of'the'first solvent 5 are molecules 6, shown by solid circles which infiltrate between the molecules 2a of the indicia and contact the surface or interface the indicia and the support sheet 1.
  • the openings between the molecules 2a of the indicia indicate the porosity afforded by the interaction of the-indicia and the first solvent which permits the second or type II solvent to pass into contacting relationship with the surface of the support sheet.
  • the adhesive solutioncoated on the surface of the support sheet 1 and on the indicia 2 provides a pressure-sensitive coating for the subsequent transfer of the indicia to a receiving surface 10...
  • theadhesive materials it isnece's'; sary to use materials which have. a good adhesion to; the surface of the support sheet. It is desirable that the pressure-sensitive adhesive be more .stronglybonded' to the surface of the support sheet 1 than to the surface of a receiving member 10, and it is preferable if the adhesive material has a relatively low sticking power so that in the step of transferring the indicia to the receiving surface 10, the remainder of the adhesive coating 3 remains on the support sheet and is not transferred over to the receiving surface.
  • Another factor to be considered is the cohesiveness of the coating 3, 3', which must be sufficient to hold the indicia on the support sheet yet permit the shear between the coating 3 on the sheet and the coating 3' on theindicia. For this reason, the use of wax in large proportions in the adhesive solution is to be avoided. However, if the cohesive force of the adhesive coating is not carefully balanced and the cohesive force between the different parts of the coating 3, 3' is great it may not be possible to effect a proper transfer of the indicia from the support sheet 1 to the receiving surface 10.
  • the cohesive character of the coating 3, 3 should be such that it will permit thedetachment of the indicia 2 from the support sheet 1 by a shearing action about the laterally peripheral boundaries of the indicia.
  • the shearing effect can be facilitated about the edges of the indicia by accenting the'detachment of the indicia by means of the phenomenon of migration.
  • the role of the adhesive coating is to retain the indicia on the support sheet until it is transferred by a pressure action to a receiving surface and then it is important for the adhesive coating to separate in a clean line about the lateral periphery of the indicia.
  • the duty of the adhesive layer in the present invention actually is, in the first part to retain on the support sheet the indicia released from the surface of the support sheet by the infiltration of the solvents and, in the second part to attract the indicia and secure it against the receiving surface.
  • the adhesive coating have a relatively dry, non-sticky nature on its surface exposed to the receiving surface.
  • the indicia 2 When the indicia 2 is applied to the support sheet 1, it has a certain degree of bonding to the support surface prior to the coating with the adhesive solution.
  • the adhesive solution When the adhesive solution is deposited on the surface of the support sheet, the infiltration of the type II or second solvent through the indicia effects a loosening of the bond between the indicia and the support sheet at the interface surface 4.
  • an adhesive having a high adhesive or sticky nature but it should be capable of attaching and fixing the indicia to the receiving surface in the transfer operation.
  • the ad hesive nature of the coating should be proportional to the ability of the indicia to adhere to the support sheet. Accordingly, the greater the adherence of the indicia to the support sheet, the greater should be the adhesion between the indicia and the receiving surface by means of the adhesive.
