Abstract

An absorbent paper product comprising indicia wherein the indicia comprise L*a*b* color wherein the L*a*b* values are outside of the boundary described by the following system of equations: { a *=−29.0 to −5.2; b *=14.0 to 49.5}→ b *=1.4916 a *+57.2563 { a *=−5.2 to 35.3; b *=49.5 to 38.9}→ b *=−0.261728 a *+48.139 { a *=35.3 to 38.3; b *=5.3 to 38.9}→ b *=−11.2 a *+434.26 { a *=38.3 to 36.3; b *=5.3 to −0.70}→ b *=3 a *−109.6 { a *=36.3 to 11.3; b *=−0.70 to −26.0}→ b * =1.012 a *−37.4356 { a *=11.3 to −20.0; b *=−26.0 to −29.3}→ b *=0.105431 a *−27.1914 { a *=−20.0 to −29.0; b *=−29.3 to 14.0}→ b *=−4.81111 a *−125.522 wherein L* is from 0 to 100.

Claims (25)

1. An absorbent paper product comprising indicia wherein the indicia comprise L*a*b* color values wherein the a* and b* values are outside the boundary described by the following system of equations:

{ a*=− 29.0 to −5.2 ; b*= 14.0 to 49.5 }→b*= 1.4916 a*+ 57.2563

{ a*=− 5.2 to 35.3 ; b*= 49.5 to 38.9 }→b*=− 0.261728 a*+ 48.139

{ a*= 35.3 to 38.3 ; b*= 5.3 to 38.9 }→b*=− 11.2 a*+ 434.26

{ a*= 38.3 to 36.3 ; b*= 5.3 to −0.70 }→b*= 3 a*− 109.6

{ a*= 36.3 to 11.3 ; b*=− 0.70 to −26.0 }→b*= 1.012 a*− 37.4356

{ a*= 11.3 to −20.0 ; b*=− 26.0 to −29.3 }→b*= 0.105431 a*− 27.1914

{ a*=− 20.0 to −29.0 ; b*=− 29.3 to 14.0 }→b*=− 4.81111 a*− 125.522

wherein L* is from 0 to 100.

2. An absorbent paper product according to claim 1 wherein the indicia comprise L*a*b* color values wherein the a* and b* values are inside the boundary described by the following system of equations:

{ a*=− 41.2 to −29.0 ; b*= 3.6 to 52.4 }→b*= 4 a*+ 168.4

{ a*=− 29 to −6.4 ; b*= 52.4 to 64.9 }→b*= 0.553097 a*+ 68.4398

{ a*=− 6.4 to 33.4 ; b*= 64.9 to 42.8 }→b*=− 0.553097 a*+ 61.3462

{ a*= 33.4 to 58.0 ; b*= 42.8 to 12.5 }→b*=− 1.23171 a*+ 83.939

{ a*= 58.0 to 25.8 ; b*= 12.5 to −28.2 }→b*= 1.26398 a*− 60.8106

{ a*= 25.8 to −9.6 ; b*=− 28.2 to −43.4 }→b*= 0.429379 a*− 39.278

{ a*=− 9.6 to −41.2 ; b*=− 43.4 to 3.6 }→b*=− 1.48734 a*− 57.6785

wherein L* is from 0 to 100.

3. An absorbent paper product according to claim 2 wherein the absorbent paper product has an MD modulus of less than about 20,000 g/cm at a load of about 15 g.

4. An absorbent paper product according to claim 3 wherein the absorbent paper product has an MD modulus of from about 500 g/cm to about 20,000 g/cm at a load of about 15 g.

5. An absorbent paper product according to claim 4 wherein the absorbent paper product has an MD modulus of from about 1000 g/cm to about 15,000 g/cm at a load of about 15 g.

6. An absorbent paper product according to claim 5 wherein the absorbent paper product has an MD modulus of from about 2000 g/cm to about 10,000 g/cm at a load of about 15 g.

7. An absorbent paper product according to claim 1 wherein the process colors are cyan, yellow, magenta, black, red, green, and blue-violet.

8. An absorbent paper product according to claim 1 wherein the product further comprises an anti-rub off coating.

9. An absorbent paper product according to claim 1 wherein the indicia are provided by halftone dots.
