     DETAILED DESCRIPTION OF THE INVENTION 
     In the composition of the present invention, the crosslinkable cationic polymer (b) suitably can comprise tertiary amino groups and/or hydroxyl groups. Preferably, (a) is a crosslinkable polymer of a vinyl lactam/dimethylaminopropyl methacrylamide/hydroxyethyl methacrylate terpolymer or a vinyl lactam/dimethylaminopropyl methacrylamide copolymer. A preferred vinyl lactam is vinyl caprolactam. A particularly preferred example of such a cationic polymer is the resin ViviPrint™ 200 manufactured by International Specialty Products (ISP). Such terpolymer preferably comprises vinyl caprolactam (VCL), dimethylaminopropyl methacrylamide (DMAPMA) and hydroxyethyl methacrylate (HEMA), uncrosslinked or crosslinked, unquatemized or quaternized, preferably quaternized and crosslinked. Suitable quaternizing agents include HCl and H 2 SO 4 . Preferably, the terpolymer comprises, by wt., 60-90% VCL, 10-30% DMAPMA and 2-10% HEMA, preferably 75-80% VCL, 13-16% DMAPMA and 4-6% HEMA. 
     Another preferred example of a cationic copolymer is the resin ViviPrint™ 131, 121 or 300, manufactured by ISP. For example, ViviPrint 131 is VP/DMAPMA copolymer neutralized with HCl. 
     The terpolymer suitably has a molecular weight of about 500,000 to about 1,500,000, preferably about 500,000 to about 1,000,000. 
     The cationic polymer suitably can be present in an amount by weight, of about 1 to about 50%, and, preferably, for ViviPrint™ 200, about 5 to about 45%, and, more preferably, of about 10 to about 40%, of the composition. 
     The colloidal silica (c) suitably are amorphous colloidal silica particles e.g. 20-150 nm. Preferred colloidal silicas are Silcron IJ-25 and IJ-50. 
     The silica gel (d) suitably are amorphous colloidal silica particles, e.g. 1.5-10μ. A preferred silica gel is Silcron G100. 
     In a preferred embodiment of the invention, the binder (e) is a vinyl acetate-ethylene copolymer e.g. Airflex® 465 Emulsion, available from Air Products. Airflex® 465 emulsion is a rapid-setting vinyl acetate-ethylene copolymer, which is a high-solids emulsion. This polymer adheres well to various substrates such as polyester, poly(ethylene terephthalate), tempered aluminum foil and polystyrene. This emulsion combines a high-solids content with a low viscosity, which is a combination that permits the addition of high-filler loadings, resulting in adhesive formulations with solid contents of 80%, or more. Furthermore, this emulsion does not thicken excessively on the addition of plasticizers which allows for the formulation of very high-solids adhesives. Airflex® 465 emulsion also is shear stable, and can be applied on high-speed packaging machines using roll, extrusion or spray equipment. The emulsion dries to a slightly tacky, clear, water-resistant film.

     Coating Process 
     To 10 g of Mix A and B in (1) was added 0.1 g of Heloxy® 67 and 0.075 Ancarez® AR 550. The viscosity was 710 cps (#3, 50 rpm LV). The coating weight was 12-13 g. A #60 rod was used for vinyl and polyester terephthalate substrates; and a #40 rod for paper. 
     To 10 g of Mix A and B in (2) was added 0.1 g of XAMA-7 (polyaziridine crosslinker) and coated on both paper and vinyl. 
     Suitable (e) binders include a latex, polyvinyl alcohol, gelatin and starch. Preferred is a latex. 
     Suitable pigments include titanium dioxide, clay, alumina and calcium carbonate.

     Example 6 
     Water, Silcron G-100, PS-10, barium sulfate, and titanium dioxide were well blended and homogenized. To this mixture was added Airflex® 465, Aquazol® 200 (20% solids), and ViviPrint™ 200 (30% solids). Using a LV Brookfield Viscometer, the viscosity was measured as ˜290 cPs ((6)4, 70 RPM). The compositions contained 22.5% solids in water.

         Step 1: Add 600 g of water to a 1.5 L beaker. 
         Step 2: Add 65 g of Silcron G-100 (ISP/Millenium), 13 g of BaSO 4 , 13 g of ViviPrint PS10 (ISP) and 2 g of TiPure TiO 2  (duPont). Homogenize. 
         Step 3: Add 130 g of Airflex 465 (Air Products). Mix thoroughly, homogenize if necessary. 
         Step 4: Add 390 g of Aquazol 200 (ISP/PCI, 20% solids in water, previously made). Mix thoroughly, homogenize if necessary. 
         Step 5: Add 197 g of ViviPrint 200 (ISP, “as is”). Mix thoroughly, homogenize if necessary.

     This coating composition was applied using a Rotary Coater Instrument equipped with either a #40 or #60 wire round rod. The resulting coating weights were ˜10 gsm or 24 gsm, respectively. To dry the coating, 3 IR driers and 3 zone heating were employed. The ovens were set for 145° C., 135° C., and 125° C. for the 10 gsm coating and 145° C., 135° C., 125° C for the 24 gsm coating.

     Example 10 below illustrates a matte, inkjet printable coating applied to white Melanex film. The coating is fast drying and exhibits water resistance. 
     Example 10 
     
         
         Step 1: Add 18.4 g of water to a 50 mL beaker. 
         Step 2: Add 3.1 g of Silcron G-100 (ISP/Millennium). Homogenize. This is vessel 1. 
         Step 3: Add 1 g of pDADMAC, 0.75 g UCAR 313 (Dow), 2.65 g of ViviPrint 200 (ISP). Mix thoroughly. This is vessel 2. 
         Step 4: Slowly add vessel 2 to vessel 1. 
         Step 5: Add 0.45 g of Ancarez AR 550 (Air Products) and mix thoroughly. Add 0.05 g Surfynol 440. Mix thoroughly, homogenize if necessary.
